Tuesday: Warming trend continues, maybe a few showers

/ at 6:45 PM

After a day in which we warmed up some 14° compared to Sunday with a high of 60° at the airport, the warming trend continues for Tuesday and beyond as surface high pressure continues to move offshore. Temperatures on Tuesday start in the low-to-mid-40s — roughly where we were for a high on Sunday — and warm into the mid-60s in the afternoon under mostly cloudy skies. A few showers will be possible at times, but any rain will be generally light. Still, y’all know how traffic can get even with the lightest of rain, so prepare accordingly.

The week ahead: Decidedly warmer, but showers hang around

/ January 21, 2024 at 10:58 PM

After a quite chilly weekend, we will be thawing out very quickly as we get into the new work week. Monday gets off to one more frigid start with lows in the mid-20s. From there, though, we start to see the arctic airmass begin to modify as a ridge builds aloft and surface high pressure shifts offshore. Monday’s high goes into the mid-50s, much warmer than we were at any point over the weekend. Then it gets downright spring-like: Tuesday warms into the mid-60s after a mid-40s start, and by Wednesday we’re in the 70s. Mid-70s take hold Thursday through Saturday ahead of a cold front, which should help to bring temperatures down a touch by Sunday.

The only fly in the ointment will be scattered shower chances beginning Tuesday and really lasting for the next few days as we sit between an upper trough to the west and ridging to the east. This will transport moisture and occasional upper-level disturbances into the area, and a surface trough along the coast will help act as a focal point for shower development. It won’t rain all the time or all day at any one spot, but all the same you’ll want rain gear handy just in case, especially heading into the weekend as the aforementioned front approaches.
