Monday night at 9 :30 p.m. is the WeatherBrains webcast I will be participating in. Click here to watch it live — or see a replay of it once it has aired. The programs typcially last about 90 minutes.
We start out cool on Monday, with lots of locations in Southwest Virginia in the 40s, but the week as a whole looks warm, with highs likely poking back up over 80 from the Roanoke Valley south and east from Wednesday onward. It still appears the work week will be totally dry or very nearly so — a cold front washing out west of us might be able to help trigger a few showers or brief storms west of Roanoke late Monday afternoon or into Monday evening, but rain chances look minimal for any given location. High pressure over the Southeast U.S. will lead to above-normal temperatures to start October (normal highs are generally upper 60s New River Valley to low-mid 70s Roanoke Valley next several days.)
The most interesting thing on our weather horizon is a strong cold front approaching by the coming weekend — and the possibility that what is now a fairly weak tropical system over the Caribbean may become entrained into the moisture ahead of the front. This feature has a chance to develop into a tropical storm — maybe some chance to become a hurricane — as it drifts north toward the Gulf of Mexico later this week. Many models do bring it into the eastern Gulf, in prime position for either the system itself or its remnant moisture to be swept northward near or over us by late in the weekend. It will give us something to watch in what appears to be a rather uneventful week of weather, locally. With or without the tropical moisture, the front late this coming weekend or early next week does appear likely to bring a solid shot of Canadian air. There may be another somewhat colder front 5-7 days later. Leaves will by be flying soon — and maybe even flurries, too, in some higher elevations over the next couple of weeks.
