Area forecast discussion, Apr 24, 12:22 PM CST, 2 hours 42 minutes before
Area Forecast Discussion National Weather Service Huntsville AL 122 PM CDT Sat Apr 24 2021 .NEAR TERM...(Tonight) Issued at 121 PM CDT Sat Apr 24 2021 Showers and thunderstorms that will develop this afternoon will be exiting our eastern counties around 00Z. Will carry a PoP in these areas into mid evening just in case this trend is too fast. The upper trough and cold front will shift quickly east overnight, with a decent and north flow may gust at 15-20 mph at times. Low clouds will envelop the area behind the front with modest cold advection. Lows should be in the middle to upper 40s. .SHORT TERM...(Sunday through Monday) Issued at 121 PM CDT Sat Apr 24 2021 A long awaited dry and warmer trend in the weather is foreseen beginning Sunday but lasting into next week. For Sunday and Monday specifically, a surface through mid level ridge axis will shift east into the Southeast U.S. Low level flow will become southerly and temperatures at 8h will warm into the 8-10C range Sunday and into the 13-16C range Monday. This will bring highs in the upper 60s to lower 70s Sunday to the upper 70s to lower 80s on Monday. Patchy fog will be possible Monday morning. .LONG TERM...(Monday night through Friday) Issued at 121 PM CDT Sat Apr 24 2021 High temperatures will continue a warming trend through mid to late week. Highs should be in the lower 80s for most areas, possibly nearing 85 Tuesday and Wednesday in northwest Alabama. The medium range models are showing a strong upper ridge in the Gulf of Mexico through the lower Atlantic coastal areas on Wednesday into Thursday. Then, model differences appear with the Canadian and ECMWF keeping the upper lows in the Great Lakes and TX/Mexican plateaus unphased. This would bring a deeper eastern U.S. trough in the northern stream southeast, along with a late week cold front. This appears to be more favored. The GFS loosely phases the lows into a stronger trough and cold front Thursday night into Friday which appears less certain given the strength of the Gulf of Mexico ridge this week. In either case, low PoPs will be mentioned Thursday into Friday before drying takes place by Friday night into Saturday (Day 8). Lows by Saturday morning may drop back into the upper 40s to lower 50s. && .AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon) Issued at 1130 AM CDT Sat Apr 24 2021 Ceilings in the 020-030agl range (MVFR) may lift or scattered into the 030-035agl range (VFR). This is not a certainty, so have opted to keep the layer as a ceiling for now. Isolated to scattered SHRA and possibly TSRA are expected to develop after 20Z in northwest into north central AL. However, due to uncertainty on TSRA, have opted for VCSH at this time from 21-23Z at KMSL and 22-01Z at KHSV. A frontal passage will shift the wind from southwest to northwest this evening with low ceilings below 010agl (IFR) expected to move in. Clearing of these clouds is expected late Sunday morning by 15-17Z with a return to VFR conditions. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE.
