The Roanoke Valley will spend a few days under a heat ridge and will push 90 degrees for the next three days. While we should be 4-5 degrees below record temps, this air mass will be close to 10 degrees above normal once we factor in the low temps, especially on Wednesday. Random showers and thunderstorms will be a concern across the region Wednesday and then as a rather strong cold front passes the area Thursday afternoon and evening, more widespread showers and storms will take place. Places east of the Blue Ridge will have the least chance of showers and storms each day.
The weekend looks great with low humidity and high temps in the low to mid 70s. Some of the mountain regions could have lows touch down in the 30s, but my hunch that is limited to the areas more to the north and northwest, out of our area. We will be blessed with another spectacular weekend.
Looking in the tropics, later today we should finally have our first hurricane of the year. Humberto should break the barrier and be upgraded later today to hurricane status. It will be a harmless storm way off very close to the Cape Islands, taking a N and NW track, lasting two-three days as a Hurricane. Gabrielle has fired back up again and is now a tropical storm again (perhaps for the first time, with many solid contentions that it did not meet criteria for a tropical storm). Bermuda is under the gun for tropical storm warnings. If Gabrielle takes the far western portion of its track, it could make landfall as a weak tropical storm in Nova Scotia, but the more preferred track is near Prince Edward Island.
It’s possible that Ingrid forms somewhere in the Southern Gulf Region and by Friday morning we have three named systems in the Atlantic Basin. While we’ve had such a benign season, it only takes one event to make a tropical season memorable. Case in point, 1992 had one tropical storm that made landfall (Danielle) and one hurricane, which was Andrew. Andrew is one of three Cat 5 systems to make landfall in the United States.
