Issued at 640 AM CDT Fri Apr 11 2025 Updated aviation discussion for 12Z TAFs. && .DISCUSSION... Issued at 236 AM CDT Fri Apr 11 2025 Mainly dry conditions have returned to the region early this Friday morning. However, a few sprinkles or even an isolated shower cannot be ruled out through midday as a secondary cold front passes through. By afternoon, lingering sky cover should decrease as deeper moisture shifts south of the region. Highs today will be much cooler than yesterday, with readings ranging from the upper 50s to lower 60s. Tonight, the core of surface high pressure will settle into the region. The resultant clear skies and calm winds will allow temperatures to drop into the 30s. Temperatures across much of southern Illinois, southwest Indiana, and western Kentucky could be cold enough for the formation of patches/areas of frost overnight. This may eventually necessitate the need for a Frost Advisory in those areas. A warming trend will begin on Saturday as an upper level ridge builds east from the Plains and southerly flow ensues on the back side of departing high pressure. By Sunday, the pressure gradient will have tightened enough to result in strong southerly winds, with sustained winds around 15 mph and gusts of 20 to 30 mph. Highs by Sunday should manage to top the 70 degree mark over the entire area. The approach and passage of our next cold front on Monday will yield the next chance of showers and perhaps a few thunderstorms. The NBM may be somewhat underdone with rain chances, but lack of moisture return may ultimately be a limiting factor. Conditions dry out for Tuesday and Wednesday before the next weather system brings rain chances back for Wednesday night into Thursday. && .AVIATION /12Z TAFS THROUGH 12Z SATURDAY/... Issued at 640 AM CDT Fri Apr 11 2025 The passage of a secondary cold front will bring a period of MVFR sky cover and the potential for a few showers or sprinkles this morning through midday. Thereafter, VFR conditions are expected as skies gradually clear throughout the afternoon into the early evening. North winds around 10 knots with gusts of 15 to 20 knots today will become calm tonight. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...None. MO...None. IN...None.
