Area Forecast Discussion National Weather Service Lincoln IL 1154 PM CDT Thu Oct 31 2013 .DISCUSSION... ISSUED 900 PM CDT Thu Oct 31 2013 The cold front has departed into Indiana, but steady light rain will affect areas east of I-57 through midnight. After midnight, no precipitation is expected, with clearing skies from SW to NE. Satellite trends confirm plenty of breaks in the clouds just across the border in Missouri, advancing steadily to the ENE. Our northern counties may see clouds linger longer due to low clouds wrapping into northern IL from Iowa. Cooler air will invade the area by morning, with lows dipping into the upper 30s NW of the IL river and dropping to the mid 40s in the SE. We trimmed a couple degrees off low temps for our WNW counties where the cold air will have the most residence time before morning. The weather grids were updated to trim the western edge of PoPs and to better align with current trends. Dry conditions still on track for after midnight. Winds will remain brisk behind the cold front, with west winds gusting into the 20-25 mph range at times overnight. Updated forecast info will be available shortly. Shimon && .AVIATION... ISSUED 1154 PM CDT Thu Oct 31 2013 MVFR clouds look to be holding tough in the post frontal airmass. Even some IFR cigs down to 700-900 ft will be possible in the first few hours of the tafs. Wrap around moisture will have an opportunity to rotate into IL on brisk west winds, before the surface and upper lows make progress to the NE. Forecast soundings are looking more pessimistic on clouds even on Friday as strato- cumulus develop in the 3500ft layer. We should remain VFR, but a bit cloudier than previous forecasts. No precip is expected, but Friday evening will see showers in N IL drop toward I-74 by midnight, or the later hours of this taf period. Winds will remain brisk from the WSW, with gusts to 22-24kt at times...mainly in response to the deepening surface low across the Great Lakes and building high pressure in the Plains. Winds should veer to the NW on Friday. Vis reductions may dip 5sm br due to saturated boundary levels, but steady winds should preclude vis dropping much lower than that the rest of tonight. Shimon && .PREV DISCUSSION... ISSUED 308 PM CDT Thu Oct 31 2013 Main concerns this package include timing of end of pcpn tonight, possibility of pcpn tomorrow night, and chances of more pcpn most of next week. Models look very similar in the overall upper level pattern through about Tuesday night, then differ with the speed of the next trough moving through Wed and Wed night, then look similar again for Thursday. On the surface, all the models look very similar, which leads to higher confidence in new forecast. SHORT TERM...Tonight through Sunday Pcpn will continue into the evening hours and should be out of most of the area by 10pm...only east of I-57, and then out of the state by midnight. The front, located between I-55 and the Illinois river will quickly push through the state and be well east of the area by midnight. However, cyclonic flow will remain over the region rest of the night and tomorrow, and continue into tomorrow night. Though most of the pcpn will be over, broken cloud cover will remain until a second mid level trough rotates through the area tomorrow night. There could be some light rain showers tomorrow night as this trough moves through, but chances are very small, so will have slight chc pops north of a Macomb to Paris line, which should get mentioned in the worded forecast. Then as high pressure builds into the middle part of the US, dry weather will dominate the area for the weekend. After slight above normal temps, afternoon highs will drop to below normal for the tomorrow and the weekend. Overnight lows should be around normal for tonight and tomorrow night, but then fall down into the 30s for Sat night. LONG TERM...Sunday night through Thursday Mid level ridging will begin the extended period with dry and slightly warmer temps. But the ridge will push through quickly and another long wave trough will develop in the western half of the US. A large frontal system will also develop in the plains early in the week, in response to the developing long wave trough. In addition a large high pressure area will develop in the mid levels in southeastern US, which should act to slow things down. So, this large frontal system will move toward the area beginning Mon night and bring a chance of pcpn to the western half of the area. However, as the mid level ridge develops, this could get delayed, but pcpn will gradually cover the entire cwa Tue through Thursday, with the greatest chances right now appearing to be Tue night and Wed. Temps will remain slightly below normal through the period. && .ILX WATCHES/WARNINGS/ADVISORIES... NONE. &&
