We could see 70 today before rain arrives
Unless the thickening clouds today keep temperatures in check, the thermometer at BWI-Marshall could threaten the 70-degree mark today. But the mild weather won't much last longer.
Forecasters are watching the approach of the next cold front, which is moving out of the Ohio Valley and due to pass through here late today. It could bring some showers, but it's also possible the rain will not make it past the Appalachian highlands.
In any case, there's colder air behind the front, and we won't see highs on Wednesday much beyond the 50-degree mark. Forecasters say skies will clear for a while, making the start of the holiday travel period on Wednesday and into Thursday pretty pleasant.
There's actually a warm front forecast to pass through our region early Thanksgiving morning. And, thanks to the perversity of weather, it could actually trigger some briefly frozen precipitation as it advances into the colder air to the north. Here's Eric the Red's take:
"This morning's run of the WRF [computer model] actually has a pronounced period of sleet north and west of Baltimore, which finally succumbs to just plain old rain by mid-day. Once the front lifts to our north, we should dry out for the remainder of Thanksgiving Day and warm up."
But there's a second, stronger cold front due to approach our region. It's likely to bring us more rain late on Thursday into Friday, forecasters said. Once that front is past us, skies will clear and temperatures for your weekend shopping will drop. Expect highs in the mid-40s and overnight lows below freezing.
It looks like the really bad holiday weather will stay to our north and west. AccuWeather.com is talking about snow in central and eastern Pennsylvania on Thanksgiving day, making driving icy on I-80 east from State College, and on the Turnpike east of Breezewood. Lake effect snows on Saturday are expected on I-90 and I-81 in New York State, and on I-80 and on I-90 from Western New York to Ohio.
Then we can look forward to the next cold front and associated precipitation, due early next week. The students at Foot's Forecast don't seem to have anything nice to say about the weather from here on into winter.
