Temperatures in the fall: you never know what you’re going to get. While some will be hanging on to summer this week, others will be tasting winter for the first time.
Ridging in the central US will bring a surge of warm air as far north as the High Plains. Southerly winds will help drive high temperatures into the 70s and 80s. That’s about ten to fifteen degrees above average! Spots like Meridian, MS and Montgomery, AL could set new record highs Tuesday afternoon.
The increase in warmth and moisture will contribute to a marginal risk of severe weather as an area of low pressure develops just east of the Rocky Mountains.
On the flip side of the coin, troughing in the upper Midwest and northeast will keep high temperatures below average by about five to ten degrees. Highs will be stuck in the 40s and 50s. Clear skies and calm winds overnight will allow temperatures in the east to drop quickly. Lows will be around the freezing mark Wednesday morning. This could be the first frost or freeze for many locations in the mid-Atlantic. Freeze Warnings and Frost Advisories will once again be in effect for major cities like Columbus, OH and Philadelphia, PA.
The low pressure system that will bring a chance of severe weather to the Central Plains today will slide east over the next few days. From lower Michigan to New York, a wintry mix of rain, ice and snow will move in by Thursday. The warm ground and dry air in place will make it difficult for snow to accumulate. It will also make forecasting a challenge. Some spots will see multiple types of precipitation, one right after the other. Regardless, slick roads and chilly temperatures will make for a tough end to the work week.
