Area forecast discussion National Weather Service Marquette Michigan 752 am EDT Sat may 30 2015 Short term...(today and tonight) issued at 458 am EDT Sat may 30 2015 The initial focus for the short term is the departing rain showers behind the cold front that moved through the area yesterday afternoon/evening. As of 4am...rain showers are currently southeast of a line from Iron Mountain to Munising. To the west...have seen an occasional report of drizzle over north central Wisconsin and visibilities have been bouncing between 8-10mi at kiwd...leading to the expectation of some light drizzle or fog. Farther to the west...the influence of the drier air seen on the 00z kinl are starting to near the western part of the County Warning Area with ceilings rising to VFR values at kcmx this past evening and in northwest Wisconsin. Expect the showers to continue to move northeast while the overall push is to the southeast (aided by the upper trough moving through northern Ontario and the surface trough continuing to move southeast through lower michigan). Thus...will show continued decreasing probability of precipitation from northwest to southeast through the morning hours...with the showers out of the u.P. By middle morning. Behind the showers...that low level dry air (associated with an approaching high) will eat away at what remains of the low clouds from northwest to southeast and produce sunny conditions over the west by early afternoon and over the central/east by middle-late afternoon. Even with the expected sunshine...the cool northerly flow will lead to temperatures 10 to 20 degrees below normal across the u.P. The coldest temperatures will occur over the northern u.P. Due to the cooling influence of Lake Superior...with areas in the north central u.P. Seeing highs in the middle-upper 40s. The high tries to nose into the area tonight...but the center of the high remains just to the north of Lake Superior. This leads to light northeasterly flow over Upper Michigan and produces concerns on how low temperatures will fall tonight. With the dry air becoming established over the u.P. This afternoon...the clear skies and precipitable water values around 0.25in (nearing record low value for kgrb sounding on 5/31 at 12z of 0.23in) would lead to a favorable radiational cooling night. But with the high staying to the north of the area...there appears to be enough of a low level gradient flow to (925mb winds of 20-25kts) to lead to some mixing and keep the best radiational cooling conditions from occurring. That being said...still think areas over the interior west will see temperatures falling below freezing and into the upper 20s in the normal cold RAWS sites. After coordination with grb...issued a freeze warning for Gogebic/Ontonagon/Iron and southern Houghton counties for tonight. For the rest of the area...the influence of the Great Lakes and the potential for slightly stronger winds should keep temperatures in the lower 30s (will likely see some bouncing of values through the night as winds briefly increase in some locations). Have issued a frost advisory for the central u.P. And the Keweenaw for the expected cold temperatures and frost. Did leave out Schoolcraft/Luce County for now...since forecasted lows are in the middle 30s and winds are expected to be higher. That led to lower confidence for widespread frost and will let the day shift take one final look. Finally...the Flood Advisory for the Michigamme river near Crystal Falls continues into early afternoon...with values staying steady about 0.1ft above action stage over the last 18-20hrs. Long term...(sunday through friday) issued at 458 am EDT Sat may 30 2015 Last 24hrs of medium range model runs remain consistent on the overall changes that will be occurring during the long term. Northern stream ridging/positive height anomaly over far western Canada/Alaska vicinity that has been a prominent feature for many weeks...and really much of this year...will be weakening as it retrogrades to the northwest of Alaska. Meanwhile...a trough will be developing over the northwest Continental U.S. Which will force downstream height rises over the Great Lakes. These changes will lead to a warmer pattern (above normal temps) during the middle and late part of the upcoming week. Prior to that...one last surge of cold air currently diving S into the upper Great Lakes will bring frosty nights (tonight and Sun night and probably even Monday night in some areas). As for precipitation...dry/Canadian air mass will dominate for the next several days under slow moving surface high pressure ridge. During the last half of the upcoming week...pattern looks active with periods of rain showers/thunderstorms and rain as the northwest Continental U.S. Trough sends energy downstream. Beginning sun...while the center of the parent surface high pressure will drift east to Quebec on sun...ridging back to the west-southwest will result in another high center developing over the chilly waters of Lake Superior in typical early warm season fashion. Slow moving shortwave trough shifting across northern Ontario and approaching Western Lake Superior may spread a fair amount of high clouds across the forecast area during the day per GFS/NAM relative humidity forecasts. Expect maximum temperatures from around 50 north to around 60 scntrl/interior west. Most Lakeside locations along Lake Superior will stay in the 40s. Underneath the surface high pressure ridge axis Sun night...radiational cooling potential across Upper Michigan is better Sun night than tonight. NAM/GFS precipitable water Sun night is similar to tonight... suggesting similar cooling potential between the 2 nights. However... the complicating factor is cloud cover as the aformentioned slow moving shortwave drifts over the upper lakes. GFS/NAM suggest scattered to perhaps broken high clouds over the area. Normally would go at or below lowest guidance given the dry air mass and surface ridge over the area...but with the cloud cover uncertainty...will stay within the lower range of the guidance temperature spread for this forecast issuance. Still looks like a frost/freeze is likely in the interior. With upper level trough drifting east of the area during the day Monday... there will be an increase in sunshine compared to sun. Surface high pressure continues to ridge back into the upper Great Lakes...so it will be another day with a mesoscale high pressure center redeveloping over Lake Superior during the afternoon...probably over Northern Lake Michigan as well. Thus...lake breezes will again be the rule...though the lake breeze off Lake Superior will not extend as far inland as on sun. In the interior away from lake cooling...temperatures should rise into the middle/upper 60s. 50s expected near the lakes. On Monday night...dry air mass continues to linger...especially central and east where precipitable water remains around a quarter inch. There is some uncertainty in how quickly pressure gradient tightens and return flow begins...but it will likely be slow enough to result in one more chilly night with some frost over the central and eastern forecast area. Continued the cooler trend from previous shift for min temperatures Monday night based on the latest guidance. Increasing moisture/return flow will yield a warmer night over the west...more notable in the areas that see downsloping under S winds. Dry weather lingers Tuesday with temperatures back close normal as 850mb temperatures rise to around 6c by midday. Expect highs around 70 west and around 60 along the Great Lakes shores. Shortwaves ejecting from the northwest Continental U.S. Trough will begin to affect the upper lakes during the Wednesday through Friday time frame. With surface high pressure to the east and low pressure troffing over the plains... warmth/moisture/instability will build north and east toward the area. Cold front drifting S and east through scntrl Canada toward the upper lakes will be a key feature for focusing shra/tsra...the potential for heavy rainfall and possibly severe storms late week. Latest wpc guidance shows front settling over Upper Michigan by Friday morning and drifting S into WI/lower Michigan by Sat morning. If the front does end up over Upper Michigan Friday morning...Thu/Fri will probably be the period most likely to see rain showers/thunderstorms and rain over the area along with potential for some heavy rainfall as GFS shows precipitable water to a little over 200pct of normal. Warming will continue Wed/Thu. Temperatures on Friday will be highly dependent on where frontal boundary is located. This will be most critical close to Lake Superior as that area will see an onshore wind if the front does drop into Upper Michigan. && Aviation...(for the 12z tafs through 12z Sunday morning) issued at 751 am EDT Sat may 30 2015 A tricky start to the taf forecast...with pockets of low clouds leading to low confidence for the first couple of hours of the forecast. These pockets have affected all three sites this morning...with it being the most persistent at kiwd. Recent drops in the visibility at the site and combined with webcams in the area indicate a combination of drizzle/fog affecting the site at the start of the forecast. Have continued that idea for the first couple of hours with slowing rising ceilings as drier low level air moves into the site. Expect similar pockets of low clouds to influence kcmx and potentially ksaw. The low clouds at ksaw are difficult to pin down as they are present at the office...but webcams upstream of ksaw Don/T show any low clouds. Thus...have trended the taf to VFR and will amend if needed if webcams indicate low clouds developing. Otherwise...as a high pressure ridge moves into the area this afternoon...expect a transition to VFR at all sites with decreasing winds. VFR conditions are then expected to prevail for the next several days. && Marine...(for the 4 am Lake Superior forecast issuance) issued at 458 am EDT Sat may 30 2015 The strongest winds through the middle of next week will occur through this afternoon...as Lake Superior is between a departing cold front and a high building into the area from Manitoba. Expect northerly winds up to 25kts this morning (and maybe some gusts to 30kts at the higher platforms) before quickly diminishing this afternoon and evening as the high builds over the area. This high will lead to light winds (largely under 15kts) through the middle of the upcoming work week. Finally...will allow the dense fog advisory over Eastern Lake Superior to expire at 5am this morning due to the drier low level air arriving with the northerly winds and the lack of fog on ship observations. && MQT watches/warnings/advisories... Upper Michigan... frost advisory from midnight EDT /11 PM CDT/ tonight to 8 am EDT /7 am CDT/ Sunday for miz001-003>006-011>013. Freeze warning from midnight EDT /11 PM CDT/ tonight to 8 am EDT /7 am CDT/ Sunday for miz002-009-010-084. Lake Superior... none. Lake Michigan... none. && $$ Short term...srf long term...rolfson aviation...srf marine...srf
