Area forecast discussion, Mar 10, 11:25 PM CST, 37 minutes before
Area Forecast Discussion National Weather Service Chicago/Romeoville, IL 1225 AM CDT Mon Mar 11 2019 .SHORT TERM... 145 PM CDT Through Monday Night... Breezy and seasonably cool conditions expected over the next 36 hours. This afternoon, high pressure is in place across much of the Great Plains and is progged to inch east across the mid Mississippi Valley by Monday evening. Stratus stretches across much of Wisconsin and northern Illinois this afternoon, but should very gradually continue to erode from the west through this evening. By late afternoon or evening, should see at least a few peeks of sunshine for much of the forecast area, then expect clearing skies overnight, with perhaps just a few mid and high clouds late. Winds will gradually taper from the frequent 30-40 mph gusts occurring this afternoon, but should still remain breezy/gusty through much of the evening and overnight. Anticipate low temps in the low to mid 20s overnight. A modest northwest breeze continues on Monday ahead of the approaching ridge. Temps should warm into the upper 30s north to lower/mid 40s south under partly cloudy to mostly sunny skies. By Monday night, the ridge axis will begin to overspread portions of the local forecast area. This should set the stage for favorable radiational cooling conditions with clear skies and very light winds. Will have to keep an eye on fog potential late Monday night into early Tuesday morning. Deubelbeiss && .LONG TERM... 211 PM CDT Tuesday through Sunday... The good news in the long term is that we will get a taste, albeit brief, of milder weather, but with that in March usually means gusty winds and some rain, and then a return to colder weather for the weekend. The upper level pattern will begin the period somewhat amplified, with a low across the desert southwest, and a ridge across the Great Lakes. Corresponding surface high pressure will be exiting from our region to the eastern Great Lakes during the day on Tuesday. This will allow mild and increasing moist southwest flow ahead of the deepening western low to shift toward the Midwest. The flattening upper ridge appears like it will hold off the increasing isentropic lift to keep most areas dry during the day Tuesday. This upper low will then bring several rounds of precipitation Tuesday night into early Thursday. The first wave come Tuesday night into Wednesday when a lead shortwave will push an elevated warm frontal feature through the area. This will be coupled with precipitable water values in excess of 1 inch which will lead to a round of rain. Instability and moisture advection is more impressive farther upstream closer to better forcing with the upper low, but there will be a batch of light to moderate rain with this first round. After subsidence/dry slotting behind this first wave, warm/moist air will continue to stream northward, meanwhile the system will eventually close off across the plains on Wednesday. This will send a surface warm front surging north across our area late in the day to the east of a deep (980 mb) surface low. While there are hints that some of the better forcing may skirt us closer to the occluding low to our north/west and also to our south across the Ohio Valley, increasing south winds and a fairly direct feed of Gulf moisture (PWATs in the 99th percentile for early March) coupled with a surge ahead of the dry slot will produce another period of warm, windy, wet and possibly thundery weather later Wednesday afternoon and Wednesday night. At this time any thunder would be isolated with only marginal instability aloft. The system dry slot will move across the area Thursday morning. Temperatures will nose upward on Wednesday, but winds and temperatures will get an added boost Wednesday night into Thursday once the warm front finally pushes north into Wisconsin. Highs in the 60s appear likely over at least the eastern half of the area Thursday ahead of the occluding cold front. Forecast soundings depict deep mixing developing during the day Thursday, with very windy conditions depicted as south-southwest winds potentially gust to 45+ mph. The surface trough/occlusion later Thursday and the eventual cold front Friday will lead to some wrap-around light rain showers that could become a few snow showers overnight and Friday. Cool northwest flow will be in place for the weekend. This will mean below normal temperatures, a mix of clouds and sun, and while the pattern is mostly dry, maybe some passing showers/flurries will be possible. KMD && .AVIATION... For the 06Z TAFs... 1225 AM...No forecast concerns this period. West/northwest winds 10-12kt will continue through sunset Monday evening. A few gusts in the 15-20kt range will be possible early this morning with prevailing gusts 15-20kts possible this afternoon. Winds will become light and variable or calm early Tuesday morning as high pressure moves across the area. Mid clouds will spread across the region in the next few hours and then scatter out by early this afternoon with skc expected tonight. cms && .LOT WATCHES/WARNINGS/ADVISORIES... IL...None. IN...None.
