Area Forecast Discussion National Weather Service Springfield MO 641 AM CDT Wed Oct 13 2021 ...AVIATION UPDATE... .SHORT TERM...(Today and tonight) Issued at 320 AM CDT Wed Oct 13 2021 Forecast Messages: 1. Showers and thunderstorms into Friday. 2. Low end risk for some strong storms toward central MO today. 3. Rounds of rainfall may lead to isolated flooding. 4. Southerly winds gusting to 30-40 mph today. 5. Much cooler this weekend. A deep low pressure system well NW of the area this morning has resulted in a cold front with a line of convection west of the area early this morning. The front will move into the area this morning then stall out over the CWA as the low moves north. Storm intensity has been decreasing with eastward progression and that trend should continue as instability is lower and inhibition is higher with eastward extent. Daytime heating may result in enough instability for some strong storms across the northern CWA with gusty winds the primary threat, but severe chances are low. Gradient winds between the 994mb surface low and a 1016mb high over the southeastern CONUS will result in gusty southerly winds today. Gusts have started to increase already this morning with peak gusts at KJLN and KSGF of 35-40 mph. Will generally see gusts in the 30-40 mph range with some occasional higher gusts. Winds will start to diminish late this afternoon and evening. Coverage of QPF should be limited to near the front today, but shortwave energy and an upper jet streak will support a round of more widespread rainfall and a more narrow area of heavy rainfall tonight, with the greatest QPF along the frontal zone, which is currently expected to be near and south of I-44. However, exactly where this sets up is still in question. Expect to see 0.5-1" in this zone with potential for 1-2". Do not expect to see any flooding with this round. .LONG TERM...(Thursday through Tuesday) Issued at 320 AM CDT Wed Oct 13 2021 The front will remain over the area Thursday, but intensity and coverage will decrease some after the shortwave and jet streak move out. An upper trough and surface low will move through the area Thursday night into Friday, resulting in increased coverage and intensity of rainfall. Rainfall ends from west to east Friday. Total QPF Thursday and Friday is currently forecast to range from around 1" along the I-44 corridor where the front should set up, to 0.5" away from the front. Greater QPF amounts are possible that may lead to some isolated flooding concerns. No other precip is forecast through the long term. Highs are forecast to range from 60 to the mid 70s (coolest NW and warmest SE) on Friday. Lows Friday night are forecast to be in the low to mid 40s, but cooler conditions are possible, especially in typical cold spots. Highs Saturday should be in the low to mid 60s, followed by Saturday night which will be very similar to Friday night. Could see some spotty frost if the coldest end of guidance verifies. Temperatures jump back up closer to normal for the rest of the forecast period. && .AVIATION...(For the 12Z TAFS through 12Z Thursday morning) Issued at 631 AM CDT Wed Oct 13 2021 A line of convection along a cold front will impact all TAF sites this morning and early afternoon. Expect gusty southerly winds ahead of the front and with any stronger thunderstorms. A decrease in shower/storm coverage is expected after the front passes through this evening before coverage and intensity of precip increases tonight. Exactly where the front and associated heavier precip sets up tonight is still somewhat uncertain, but the greatest chances are near KSGF and KBBG. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE.
