Tuesday’s forecast: Getting springier

/ March 11, 2024 at 7:44 PM

After one more somewhat chilly night — expect low 40s across much of the metro, with mid-to-upper 30s possible further inland — we start a warming trend that’ll get us into the 80s by the end of the week. Tuesday looks rather delightful: expect highs to top out in the low 70s away from the locally cooler coastline. Comfortably dry air will be in place with relative humidity bottoming out around 30% in the afternoon, and we’ll keep a solid amount of sunshine throughout the day. Winds will start to swing more southwesterly in the afternoon and kick up to around 5-10 MPH. Not bad!

Sunday: A nice day ahead

/ March 9, 2024 at 8:43 PM

After the cold front that helped instigate quite a busy morning of weather gets offshore, we end up with a rather nice Sunday as cloud cover clears out, leaving mostly sunny skies in its wake. Temperatures will start in the low 50s and warm to the upper 60s to around 70° in the afternoon. The only fly in the ointment will be the breeze: expect gusty conditions throughout the day as high pressure builds in, with winds 10-15 MPH perhaps gusting to 25-30 MPH at times.
