Unsettled conditions continue...
>> Tuesday, October 26, 2010
A powerhouse storm system is rapidly deepening in the Midwest today, and that will drive a cold front our way. The barometric pressure on that Midwest low will bottom out all of the way down to below 960mb.....as low as a strong hurricane. Up in Indiana and Ohio, a 'high risk' of severe weather is in place this morning, and the 'slight risk' area extends all of the way from southern Mississippi through the Tennessee Valley, western Carolinas into New York.
For our area, we saw a batch of rain with embedded lightning rapidly move through this morning. For the rest of the day, while a few isolated showers or storms could develop, the day looks largely dry, mild, and breezy. Highs will range from the upper 70s to the lower 80s.
A squall line out ahead of the cold front in the Midwest will race southeastward and largely hold together as it moves into our area. At this point, it looks like that line of showers and storms could roll into the Piedmont after midnight tonight, and then scattered showers and storms will remain a possibility Wednesday. Some storms could be severe, and we will watch the potential closely.
The system will exit the region by Thursday, and significantly cooler air will arrive for Friday and the Halloween weekend. Highs Friday and Saturday will be in the 60s, and I still think some frost is possible in some spots Saturday morning.
The weather still looks good for the trick-or-treaters this weekend.
