DAYS 1-5 (JULY 15-19)
An area of high pressure moves in from the west today providing warm but dry air. The high slips to the south with a little more in the way of humidity but still fairly comfortable Tuesday, but when a warm front comes across the region in the evening you’ll notice the humidity start to elevate more significantly, setting up 3 classic humid summer days. In the warm sector between behind that warm front and ahead of a cold front we run risk of a few showers and thunderstorms Wednesday, then with the front in the area and the remnant moisture from Barry coming across the region Thursday, that will be when we see the most numerous shower and thunderstorm activity. The weather will dry out Friday, but the air will not, and it will be a hot and humid day but without the thunderstorm risk.
TODAY: Mostly sunny. Highs 80-87, coolest coast. Wind light variable with sea breezes.

TUESDAY: Partly sunny. More humid. Highs 82-89. Wind W 5-15 MPH.

DAYS 6-10 (JULY 20-24)
July 20-21 weekend will be very warm to hot but with lowering humidity and only a risk of a passing shower/thunderstorm later on July 20. Generally west to east flow pattern will dominate with mean high pressure ridge Midwest to Upper Plains with temperatures slightly above normal to near normal later in the period, plenty of dry weather but also the risk of a passing shower or thunderstorm at times.
DAYS 11-15 (JULY 25-29)
Overall pattern similar, but a slightly westward movement of the high pressure ridge in the center may increase the risk of showers and thunderstorms slightly here, though still not a return to a very wet pattern. Much of the time would be rain-free. Temperatures closer to normal.
