Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 236 PM EDT Tue Oct 21 2025 Valid 00Z Wed Oct 22 2025 - 00Z Fri Oct 24 2025 ...Chilly and showery weather across the Great Lakes with lake-effect thunderstorm bands possible near Lake Erie today and Wednesday... ...Late October near record warmth across southern Texas today... Much of the unsettled weather through the next couple of days will remain across the Northern Tier states as another system follows behind weakening low pressure moving towards the Canadian Maritimes. The main impacts with this system are the lake-enhanced/lake-effect showers and thunderstorms which are expected to be most intense near and downwind of Lake Erie today and Wednesday. Eventually, showers should move across the Appalachians today, reaching into the Mid-Atlantic states and into New England tonight ahead of the cold front. The twin system will likewise lift northward into the Canadian Maritimes Wednesday night with much of the rain over New England tapered off by then. Colder and drier weather along with gusty winds will expand from the Midwest and Ohio Valley into the Mid-Atlantic on Wednesday as chilly and showery weather persists across the Great Lakes into Thursday. Across the south, a few record high temperatures are forecast this afternoon for southern Texas where temperatures will once again soar well into the 90s. Due to breezy and dry conditions, there is an enhanced risk of fire weather concerns across north-central Texas today. Across the Northwest, dry weather will prevail before a series of cold fronts leads to increasing precipitation coverage along the coastline beyond Wednesday. Further south, scattered thunderstorms tied to a shortwave trough are expected across the Great Basin tomorrow, which will be largely beneficial as the region remains under drought conditions.
