Area forecast discussion National Weather Service Marquette Michigan 1032 am EDT Tuesday Jul 22 2014 Update... issued at 1031 am EDT Tuesday Jul 22 2014 Reduced probability of precipitation for today in several areas with showers/T storms being confined along the frontal boundary and the pre-frontal troughs. As of 13z...low pressure was situated over Isle Royal in Northwestern Lake Superior. A line of showers and thunderstorms over north central Upper Michigan at 14z will continue their eastward progression through the afternoon as the low pressure system moves into Quebec /by about 00z/. Still seeing around 1000 j/kg of MUCAPE across the east this morning...so with the front assume this will be enough to keep them going for now. Will lose instability as the day progresses though...so do not expect much in the way of severe weather/isolated at best. Main thing we have been seeing with storms this morning is heavy rain and marginally severe winds. Kept scattered showers/T storms in the forecast over the northwest this afternoon as wrap around moisture behind the exiting low could briefly bring another round of precipitation in...which is currently observed on radar. With seiching detected on Western Lake Superior with the earlier storms...upgraded the swim risk to moderate this afternoon for Marquette and Alger counties. With strong winds moving across the lake due to the low pressure system and the storms...felt this was warranted. Winds behind the front will become west-northwesterly late this afternoon...which will kick waves into the 3 to 4 foot range. Onshore flow...3 to 4 foot waves...and possible water level fluctuations with any seiching could develop strong rip currents...particularly in areas with pre-existing rip channels within the sandbars. This would be mainly Alger County beaches and Middle Bay in Marquette. && Short term...(today and tonight) issued at 509 am EDT Tuesday Jul 22 2014 Severe mesoscale convective system is currently over the western County Warning Area...which puts the focus in the short term on the next 12 or fewer hours. Expect the mesoscale convective system to continue east in line with NCEP high-res WRF arw/nmm and NSSL WRF. Should see overall intensity/severity of storms decrease as they move east due to decreasing instability over the eastern County Warning Area. Severe potential will continue over mainly the western half of the County Warning Area /what portion that is still ahead of the squall line/. Main threat will continue to be damaging winds...with a marginal hail threat also possible. Have bulk ot precipitation out of the County Warning Area by 00z Wednesday...with some lingering showers until 06z Wednesday. Long term...(wednesday through monday) issued at 509 am EDT Tuesday Jul 22 2014 Over the next few Days...Ridge will build north through The Rockies into north central Canada...forcing a trough to deepen over eastern North America. For Upper Michigan...this will bring about a return to cooler weather though temperatures will only briefly fall back below normal for late July. Flow will relax/deamplify a bit heading into the weekend...allowing for some warming...and then the eastern trough will reamplify significantly next week. As a result...temperatures next week will fall back more notably below normal as we wrap up July. As for precipitation...dry weather during the last half of the work week on the backside of the eastern trough will trend more unsettled over the weekend as flow relaxes and shortwave energy tracks east-southeast into the Great Lakes. Next week...precipitation chances will revolve around where axis of amplifying trough sets up and how amplified the trough becomes. With recent European model (ecmwf) runs indicating a large middle/upper level low developing over the Great Lakes region... unsettled weather could linger early next week. Beginning Wed/Thu...a quiet period of weather is expected as upstream middle/upper ridge extending from The Rockies to north central Canada supports surface high pressure settling into the Great Lakes region. A shortwave dropping southeast through northern Ontario into the eastern trough Thursday will push a surface trough S toward Lake Superior. Rain showers associated with feature will stay north and east of Lake Superior as shortwave will be too far to the north and east of forecast area. Wednesday will be the coolest day of the two under weakening gradient nearly flow ahead of approaching high. It will be coolest along Lake Superior east of kmqt where temperatures Lakeside will struggle to get out of the 50s with long fetch of wind across the lake. In the interior...mixing to 850-800mb on forecast soundings yields maximum temperatures into the low/middle 70s. 850mb temperatures rise a few degrees for Thursday...and this should result in interior maximum temperatures rising well into the 70s to near 80f. Under a dry air mass (precipitable water 40-50pct of normal) with light/calm wind...Wednesday night will be a chilly night. Favored min temperatures at or below the lowest available guidance. Traditional cold spots may slip just below 40f. Should be able to get one more dry day in on Friday though there are indications of a shortwave pushing through the deamplifying ridge. Given rather weak 850mb flow/warm air advection into Upper Michigan...will maintain a dry forecast Friday. Over the weekend and on into Monday...shortwave energy will track east-southeast into the upper Great Lakes...followed by reamplification of the eastern trough. This evolution of the pattern will provide the potential for scattered rain showers...and perhaps some thunder at times Sat/sun. && Aviation...(for the 12z tafs through 12z Wednesday morning) issued at 738 am EDT Tuesday Jul 22 2014 Large complex of thunderstorms over the region will move east today. Low level moisture behind the complex will lead to lowered ceilings this afternoon before lifting this evening as drier air moves in. && Marine...(for the 4 am Lake Superior forecast issuance) issued at 509 am EDT Tuesday Jul 22 2014 A complex of thunderstorms is moving across Lake Superior early this morning...with severe winds and marginally severe hail possible along the squall line. The thunderstorms will move to east of the lake by this evening. In addition to possible severe winds along the squall line...west winds may increase for a period behind the line. High pressure will settle into the Great Lakes late Wednesday through Sat...providing a period of light winds. On a final note...fog will continue to expand on Lake Superior today before drier air spreads southeast...clearing the fog from northwest to southeast later today and tonight. && MQT watches/warnings/advisories...
