Rest of the work week: Turning summer-like

/ April 1, 2025 at 10:33 PM

High pressure will continue to keep the weather generally on the quiet side for the rest of the work week. It’s also going to help contribute to the warmest weather so far this year starting Thursday and lasting into the weekend. A bit of onshore flow will keep Wednesday’s temperatures capped to the low 80s in the afternoon under a mix of sun and clouds. From there, winds go more southerly as high pressure at the surface slips offshore. Ridging building in aloft creates a bit of a “heat dome,” and the combination of both will help bring along the warmest weather so far in 2025. Expect highs to top out around 85° on Thursday and 86° on Friday with a mix of sun and clouds each day. Lows will be even warmer, with mid-60s expected each morning that could challenge record warm low temperatures. This warmth looks to stick around into Bridge Run weekend, too, before the next front arrives Sunday night into Monday.

Tuesday: Quieter, still warm

After a raucous evening, we’ll have a much quieter Tuesday ahead as high pressure builds back in behind the cold front. The post-frontal airmass won’t feel much like a cold front came by, though, as temperatures will only come in a couple clicks below where they did on Monday (83° ended up as the day’s high temperature). Generally speaking, expect lows in the low 60s to warm to the low 80s in the afternoon under mostly sunny skies.
