Ward && .PREV DISCUSSION... /Issued 228 PM CDT Wed Sep 22 2021/ SHORT TERM...Today through Tomorrow Night... After most locations this morning starting the day in the 40s with a few locations in the upper 30s, a nice warm up is on pace for this afternoon. Current obs shows an established 1026 hPa broad sfc high translating from H500 ridge in place over the Panhandles. In-conjunction with southwest winds of of 10-20 MPH with higher gusts at times due to good mixing under clear skies, many locations are already in the 70s going into the afternoon hours. Have went slightly above the guidance for high temperatures today given the steady climb in temperatures with values topping out in the 79-84 degrees range. Another cool night for parts of the western Panhandles this evening with some mid to upper 40s. temperatures while the remainder of the Panhandles will be in the low to mid 50s. Similar pattern in store for tomorrow with H500 ridge over the Panhandles with large scale subsidence in the column. Southwest sfc winds will advect slightly warmer air into the Panhandles compared to today. High temperatures tomorrow will range from the mid 80s to around 90 degrees in some locations as dry conditions continue. Meccariello LONG TERM...Friday through Tuesday Night... High pressure over the western CONUS will gradually shift east through the extended. Upper level trough will move across the central CONUS and over the Great Lakes region on Friday. There may be a brief weak cold front that clips and dissolves over the northern Panhandles. Right now it does not appear that there will be enough moisture and lift with the front to get any storms to develop, but will still be open to adding pops if needed. While the ridge shifts east over the central CONUS the temperatures will continue to be on the warm side, with highs in the mid 80s to lower 90s. The main focus of the extended will be the Monday and Tuesday period. While the forecast currently remains dry there continues to be a hint at a cutoff low developing over southern AZ/NM. This would help pull up Gulf moisture and bring the potential for showers and storms to the Panhandles across the south on Monday and the entire Panhandles on Tuesday. We will continue to monitor the forecast and update as necessary. Weber AVIATION...18Z TAFS... VFR conditions expected throughout the 18Z TAF period.
