5/27 – Night Rob’s “Rounding Out May” Friday Evening Forecast

The big H (high pressure)

will continue to dominate the weather pattern over the weekend.

A weak upper low-pressure system could form in the eastern Gulf of Mexico over the weekend, but shower activity is expected to remain offshore.

Today and Saturday are expected to be nearly cloud-free with comfortably low humidity. As the surface high pressure slips to our east on Sunday, winds will gradually turn onshore, increasing moisture and relative humidity values somewhat, but it’ll hardly be noticeable. In short, a rather splendid holiday weekend is coming your way, with lows in the 60s both Friday and Saturday nights. High temps will be warm in the upper 80s.

A southeast flow regime will set up Memorial Day and Tuesday, bringing a gradually deeper moisture feed into the region. A minor disturbance parked over the eastern Gulf of Mexico will begin asserting some influence then. This will allow for shower and thunderstorm activity to begin forming along weak sea-breeze boundary boundaries as early as mid-morning Tuesday.
Hotter temps are possible as we progress through the week, with afternoons nudging 90 by Wednesday. Overnight will again be in the low-mid 70s by late week.
