Rest of the work week: Stormy Wednesday, then cooling off

/ April 2, 2024 at 9:46 PM

This stretch of warmer-than-normal temperatures comes to an end on Wednesday as a cold front moves through the area. Showers and thunderstorms will be ongoing ahead of the front, and there will be a risk for a few of those storms to be on the strong to severe side. Damaging wind gusts will be the main concern, but a tornado or two can’t be totally ruled out as the line pushes eastward. If storms take a little longer to get here, that could increase the severe weather threat as well. I’d be prepared for a somewhat stormy morning commute. The good news is that the front should clear the area by evening, sweeping showers and storms offshore and allowing cooler and drier air to work into the area. Windy conditions will be expected so be careful on the bridges.

From there, temperatures run several degrees below normal for the next few days, including Bridge Run weekend. Thursday will be a much sunnier day than Wednesday, but will run almost 10° cooler in the wake of the front. Expect highs to top out in the upper 60s to around 70° in the afternoon. Friday will start even cooler, with lows in the mid-40s yielding to highs in the upper 60s once again under mostly sunny skies.

We’ll start the Bridge Run in the mid-40s and warm to the mid-60s in the afternoon under mostly sunny skies. Dewpoints will run in the low 30s in the morning, dropping to the upper 20s in the afternoon as daytime heating mixes down even drier air. All in all, sweat should be a rather efficient cooling mechanism, and there are otherwise no weather concerns.

The week ahead: Very warm start to April followed by a below-normal cooldown

We’ll get April off to an almost early June-like start before a front comes through Wednesday and knocks temperatures down to more comfortable levels heading into Bridge Run weekend. (In fact, many of y’all might find it a little chilly!)

Friday & Easter weekend: Picture-perfect

/ March 28, 2024 at 10:35 PM

We’ve got no weather concerns for Good Friday and the Easter weekend. High pressure will be in control, and skies will be predominantly sunny for the next few days as a result. Temperatures will be on a warming trend throughout the period. We start Friday in the mid-40s and warm to the low 70s in the afternoon with full sunshine and low humidity. As high pressure at the surface shifts offshore a bit, temperatures will moderate. Expect Saturday to start around 50° and warm to the mid-to-upper 70s, while Easter Sunday will feature lows in the mid-50s and highs in the low 80s in the afternoon. All in all, a great weekend to get outside a bit (just mind the pollen!)

Thursday: Improving weather heading into Easter weekend

/ March 27, 2024 at 9:56 PM

Showers will be coming to an end Thursday morning, yielding a quiet and increasingly warm period for Good Friday and Easter weekend. We should see the rain exit the area by midday, and from there, cloud cover will diminish. It’ll be a cool day in the wake of a cold front; expect highs to only top out in the mid-60s in the afternoon. The breeze will kick up at times as cooler air moves into the area behind the front as well, but it shouldn’t be too terribly gusty, either.
