Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings.
March 30, 20224 yr Author Update on this watch The severe weather threat for Tornado Watch 79 continues. SUMMARY...A damaging wind and brief tornado threat will transition to primarily a damaging wind threat. DISCUSSION...A strongly forced squall line continues east across watch 79. The PAH VWP shows very strong 0-1km SRH in excess of 600 m2/s2. This has resulted in several mesovorticies to develop along the squall line. However, limited instability seems to have lessened the longevity of any of these mesovorticies. Dewpoints are still in the upper 50s ahead of the line which could be sufficient for a few QLCS tornadoes in the next hour or two. However, dewpoints in the eastern portions of the watch are near 50F with only modest increases expected in the next 1 to 2 hours. Therefore, considering the very strong low-level jet (in excess of 80 knots per the PAH VWP), damaging wind gusts will remain a threat along the squall line. However, the tornado threat will likely lessen across eastern portions of the watch. A damaging wind threat may persist north and east of watch 79, which could necessitate a downstream watch. However, lightning has reduced significantly along northern portions of the line which could indicate earlier weakening of the line. Therefore, storm trends will likely be monitored over the next hour or so before any decisions on a downstream watch are made.
