Area forecast discussion National Weather Service Marquette Michigan 348 am EDT Sat Sep 20 2014 Short term...(this evening through saturday) issued at 359 PM EDT Friday Sep 19 2014 Main concerns during this time period is the gusty wind this afternoon along with shower and thunderstorm potential tonight and Saturday. This afternoon...the main issue this afternoon is the continued strong wind gusts across the region. This is due to a very tight pressure gradient between strong high pressure departing over the northeast and strengthening low pressure pushing from Manitoba into Ontario. Modeled 850mb winds are prognosticated to be around 40 to 45 knots across the area. This is also supported by the MQT VAD wind profiles. While we may not actually able to mix up to 850mb...it does look like we could mix to near 900mb which would easily give wind gusts around 30 to 35 miles per hour with a few gusts close to 40 miles per hour...especially over the central and eastern u.P. As the gradient shifts eastward by late afternoon expect winds to diminish over the western half of the Upper Peninsula...however...the east may see stronger gusts through the early evening hours. As far as precipitation GOES...models continue to slow the precipitation movement into the Upper Peninsula. A warm front will continue to lift north of the u.P. Late this afternoon...allowing showers and a few thunderstorms to develop. This will remain mainly over the far western u.P. Where the better isentropic ascent and increased moisture remains. Additionally...the better system forcing will remain north and west of the u.P. As shown by analyzing deep layer qdiv along with deep layer relative humidity. Tonight through Saturday...a cold front will approach the upper Great Lakes region tonight as the surface low continues across Ontario. The better forcing through tonight will remain over mainly the north half of the Upper Peninsula...closer to the low pressure center. Have generally placed the best probability of precipitation over Lake Superior...however...an increased chance of showers and a few thunderstorms will be possible as the cold front pushes through the region as shown by analyzing 850mb Theta-E along with surface winds. The increased instability tonight will come from cooler air aloft associated with an upper level 500mb shortwave prognosticated to push across the region overnight. Plenty of moisture will remain in place for showers and thunderstorms as sounding remain fairly moist and 1000-500mb relative humidity values remain fairly high. The cold front will be over the Eastern Upper Peninsula by 18z Saturday...pushing most of the shower and thunderstorm potential over the far eastern u.P. A few thunderstorms could be strong Saturday afternoon ahead of the cold front over the far eastern u.P. Saturday afternoon as the shortwave and cold front become nearly collocated while shear values around around 35 to 40 knots perpendicular to the front. Strong wind gusts and small hail would be the main threat. By late in the day Saturday...additional showers and an isolated thunderstorm or two will begin pushing in over the far west as the next 500mb shortwave rotates into the the area. Long term...(sunday through friday) issued at 343 am EDT Sat Sep 20 2014 On Sunday...the pv anomaly currently over central Alberta will be just south of the area. This will allow for low pressure to develop Saturday night into Sunday along the front which is expected to move through the area this afternoon and this evening. Expect any rain associated with this wave to be focused near the Michigan/WI border Sunday morning where the best moisture and frontogenetic forcing will be located. However...this should move out by afternoon with high pressure and anticyclonic flow moving in during the day. As such...will continue with chance probability of precipitation across the east half of the forecast area Sun morning. With strong cold advection and a tightening pressure gradient...it will be quite raw Sun morning with gusty north winds and temperatures only in the 40s. Temperatures should rebound some Sun afternoon as the sun comes out...but the worry is that areas closer to Lake Superior may stay in the clouds for much of the day due to the upslope northerly flow and continued low level moisture per model soundings. Will therefore trend toward the lower end of guidance for Sunday with temperatures near Lake Superior in the low-middle 50s while areas closer to the WI border will be close to 60. Sun night into Monday will be quite tranquil with high pressure in control. Would not be shocked to see some frost Sun night/Monday morning with clearing skies and light winds due to precipitable water values under 0.40 inch. In fact...even the native NAM guidance suggests temperatures near freezing at MQT. Will therefore expand patchy frost for most inland locations in the Upper Peninsula. The east may see the coldest temperatures Monday morning due to the coldest temperatures aloft. Otherwise...Monday will be a pleasant autumn day with mostly sunny skies and temperatures in the 60s as 850mb temperatures rise to +10 by Monday evening. Tuesday through Friday...looks like a quiet and Indian Summer type setup for the week with building heights across the region Midwest and Great Lakes...leading to generally dry and warm conditions. Only chance for rain would be Wednesday night into Thursday with the GFS and European model (ecmwf) suggesting a weak upper disturbance moving through the area in the west-northwest flow aloft. Otherwise...expect temperatures well into the 70s for much of the time period. Warmest day may be Friday with the GFS and European model (ecmwf) suggesting 850mb temperatures of +14 ahead of a developing trough over the High Plains. && Aviation...(for the 06z tafs through 06z Saturday night) issued at 119 am EDT Sat Sep 20 2014 Expect ceilings to gradually deteriorate to MVFR and then IFR at all 3 taf sites by sunrise as SW flow advects more low level moisture into Upper Michigan in advance of an aprchg cold fnt. Best chance for some LIFR conditions will be at cmx...where wind shift to a more favorable upslope west direction coincident with the arrival of the fnt will enhance upslope cooling. There will be some -shra...and even an elevated ts is possible...but no sgnft visibility restrictions are likely. As dry air moves into the area on Sat behind the frontal passage...conditions will improve to VFR. But another trough will swing through the area this evening...and some low clouds/MVFR or even IFR ceilings may move in off lake supply. && Marine...(for the 4 PM Lake Superior forecast issuance) issued at 359 PM EDT Friday Sep 19 2014 As a strong pressure gradient linger over the eastern half of Lake Superior...expect strong southerly winds to gust to 20 to 30 knots through the evening hours. A few gales to 35 knots will be possible for the higher platforms and closer to the Upper Michigan shoreline through this evening. These gusty south winds will gradually diminish across the east half of the lake overnight tonight through Saturday as the trough moves across Lake Superior. Expect a period of westerly winds of up to 20 knots Saturday afternoon and northwest winds to 20 knots Sunday behind this trough. Winds will remain under 20 knots through much of next week as a series of high pressure systems moves over the upper Great Lakes. It is possible...however...that wind could gust to 25 knots Monday afternoon as a fast moving trough swings across Lake Superior. && MQT watches/warnings/advisories... Upper Michigan... none. Lake Superior... none. Lake Michigan... none. && $$ Short term...kec long term...mrd aviation...kc marine...kec
