Lingering showers and storms expected across the Southeast today and Florida through Monday… …Above average temperatures forecast throughout the Southwest, with below average readings for most locations east of the Rockies… Strong high pressure over the central U.S. today is set to slide eastward by early this week and will allow for mostly tranquil weather conditions across the Nation. A lingering frontal boundary along the Southeast will produce additional scattered showers and thunderstorms through tonight across the Carolinas, Georgia, and northern Florida. Rainfall amounts are expected to remain mostly light as the activity quickly races to the east, with rainfall chances on Monday confined to the Florida Peninsula. As the aforementioned frontal boundary crosses central Florida to start the new workweek, a few storms could strengthen enough to contain damaging wind gusts and hail. The Storm Prediction Center has issued a Marginal Risk (level 1/5) for severe weather across parts of the central and southern Florida Peninsula in order to highlight this potential. Outside of a few rain and snow showers across New England associated with an approaching cold front on Sunday night, the only other areas with notable precipitation will be linked to a low pressure system and attached cold front stretching from the Upper Great Lakes to the central Plains Monday night. Rainfall amounts are expected to remain meager and mostly under a half inch through Tuesday as the system swings into Midwest and Ohio Valley. Temperatures across the country will remain split today, with warmth in the Southwest and cooler than average highs across the central and eastern United States. As high pressure weakens and slides east, a gradual warm up can be expected east of the Rockies. The greatest turnaround is anticipated over the southern Plains, where highs in the 60s today could be replaced by 80s on Tuesday. Meanwhile, lows into the 20s and 30s this morning are likely to lead to frost/freeze concerns throughout the Midwest and parts of the Ohio Valley. Chilly morning temperatures are also expected to linger on Monday, before cool weather erodes to the Northeast on Tuesday with portions the Appalachians, Mid-Atlantic, and Northeast waking up to frosty temperatures in the 30s.
