8/4 – Brittany’s “Slight Changes Ahead” Thursday Evening Forecast
Upper ridging to the west and east with troughing across the local area. This pattern has been rather stubborn to remain over the area for much of the last week, with only minor differences from day to day. Precipitable water values continue to run above 2 inches, and with convective temperatures running in the mid to upper 80s, scattered thunderstorms have been the rule of the day. While most areas only see a little rain, isolated spots receive a couple of inches of rain in an hour or so.
The Bermuda Ridge attempts to build into the area from the east over the next few days. The one difference this would bring is somewhat drier air in the mid levels as the day progresses tomorrow, continuing through midday Saturday. Precipitable water values drop from over 2 inches to about 1.7 inches. While this won`t cut off precipitation entirely, it will reduce the threat of excessive rainfall a good amount for Friday. Moisture does start to return late in the day Saturday, with precipitation chances again increasing. Sunday and beyond, no large changes in the pattern. Isolated patches of very heavy rainfall will remain a threat early next week.
