The week ahead: Stormy start, but a lovely mid-week

/ at 5:19 PM

The upcoming week will get off to a fairly stormy start on Monday, but we’ll see things calm down and cool off a little bit for a few days before another storm system affects the area over the weekend.

Sunday: Dry most of the day, but showers should arrive late

/ February 10, 2024 at 7:16 PM

Sunday will be one last warm and largely rain-free day before shower chances arrive in the evening. Temperatures Sunday start in the mid-50s — 10°+ above normal for this point in the year — and head to the mid-70s as warmer and more moist air continues to surge into the area ahead of a storm system approaching from the west. Skies will remain mostly cloudy, though a few breaks in the clouds will still be possible especially in the morning.

By evening, we should start to see some shower activity begin to move in from the west. Guidance increasingly suggests that the best chance for showers Sunday will be found later in the evening and generally inland of 17-A. That being said, it looks like we get much of Sunday in without precipitation; just be ready for some rain as you head to and from any Super Bowl plans you may have.

Weekend forecast: Unseasonably warm; showers hold off until Sunday evening

/ February 9, 2024 at 10:03 PM

After reaching 72° today, we’ll aim even warmer on Saturday despite persistent cloud cover (don’t worry, the sun will peek through from time to time). We start the day in the low 50s — about 10° warmer than normal for February — before heading solidly into the mid-70s in the afternoon.

Sunday will start even warmer, with lows in the mid-to-upper 50s yielding to highs in the mid-70s in the afternoon. We should get much of the daylight hours in rain-free, but shower chances will be increasing as we get later into the afternoon and especially into the evening. The bulk of this rain falls Monday and could come along with some thunder as well. But let’s not think of Monday if we can help it…enjoy the weekend!

Friday & the weekend: Warming trend continues as 70s return; showers possible Sunday

/ at 6:05 PM

After peaking in the mid-60s on Thursday, temperatures will continue to warm heading into Friday and the weekend despite persistent cloud cover. We start Friday much warmer than the previous several days, with a low temperature in the mid-40s across much of the area. Temperatures will climb to about 70° despite the mostly cloudy skies, several degrees above normal for February 9.

Saturday will be a warmer version of Friday. Cloud cover will persist, with peeks of sun from time to time, but we start the day about 5-7° warmer than we started Friday with lows in the low 50s. Afternoon high temperatures should reach the mid-70s as southerly flow continues to bring warmer air into the area.

Sunday starts even warmer, with lows barely clearing below 60° in the morning, well above normal for this point in the year. Temperatures will warm back to the mid-70s in the afternoon. We stay rain-free for the first part of Sunday, but we should start to see some shower activity work into the area later in the afternoon into the evening as a storm system affects the area; much of this rain falls Monday, though, before temperatures turn back toward normal for Tuesday.

Thursday: Another chilly start, but a subtly warmer afternoon

/ February 7, 2024 at 6:48 PM

We have another chilly start ahead on Thursday as lows drop to the low-to-mid-30s across much of the metro one more time as high pressure moves overhead. We’ll see mostly sunny skies for a fair bit of Thursday before high pressure begins to slip further offshore and cloud cover starts to increase later in the day. Temperatures will show signs of a subtle warming trend as we top out in the low to mid-60s Thursday afternoon, a few degrees warmer than we have been the past couple days. Overall, it’ll end up being a fairly climatologically typical February day after the cooler-than-normal start.

Rest of the work week: Winds diminishing, turning warmer

/ February 6, 2024 at 6:51 PM

We’re just about done with the chillier weather for a few days, but first, Wednesday awaits. Lows on Wednesday should flirt with freezing, and continued breezy northerly winds will help it feel like the mid-20s. You’ll want to dress in layers to start, though you should be able to shed a layer or two later in the day as temperatures approach 60° and winds, mercifully, continue to die down.

There is a risk for some minor coastal flooding with the 5:33am high tide, though I wouldn’t be surprised to see the forecast of 7.3-7.5′ revised downward given the past two mornings have come in lower than expected. (Watch this be the one time the tide does exactly what the evening blog post says it will.) In any event, any flooding issues should be resolved before the bulk of the commute, but if you are an early commuter and downtown is in your plans, keep an eye out for possible flooded or closed roads.
