Our weather pattern will remain unsettled until a strong cold front moves through late Friday.

Tonight: Partly to mostly cloudy with patchy drizzle possible overnight and areas of fog

Lows: 50s | Wind: E 5-10 mph

Thursday: Early morning drizzle, then partly to mostly cloudy and warm.

Highs: Upper 70s | Wind: SE 10-15 mph

Friday: Partly sunny, warm, and humid. Showers & thunderstorms by late afternoon. Some very heavy.

Highs: Upper 70s to around 80 degrees | Wind: SSW 10-20 mph

With a weak weather boundary over the area, winds have shifted out of the east and are bringing in some low level moisture and low clouds.  Late tonight some areas of fog may develop and patchy drizzle will also be possible.

During the day tomorrow, that front/weather boundary will make a u-turn and move back northward as a warm front. Skies may brighten during the day as temperatures head back into upper 70s. On Friday, it will be partly sunny, warm and muggy with highs approaching 80 degrees.  Here's a simulation of temperatures Friday afternoon.

During the late afternoon through evening hours, Friday, a very strong cold front will approach the area. Widespread showers and thunderstorms will become likely. Strong winds and excessive rainfall are possible with some of the stronger cells. Skies will clear over the weekend with much cooler air arriving.
