10/10 – Brittany’s “Warm & Sunny” Monday Evening Forecast
Overall, a fairly tranquil day across the region with mostly sunny skies. Speaking of sun, plenty of insolation has occurred allowing for the boundary layer to mix quite effectively this afternoon. Winds, especially closer to coastal areas have been in the 10-15 kt range. This will decrease the moment we decouple this afternoon.
Rainfall is looking like a safe bet on Wednesday. Upstream, a surface front and parent H5 trough will be moving toward our region and perhaps some tropical moisture from the Bay of Campeche will get caught up in the active southwesterly flow allowing for at least some beneficial rainfall (albeit nothing to write home about in terms of QPF). Depending on timing of the frontal passage, some lingering shower activity may be possible during the morning hours on Thursday before a drier trend takes place across the region with cold air advection setting up.
