Rain coming to an end Friday, weekend looks chilly but quite sunny

/ February 18, 2021 at 9:46 PM

We have a chilly but mostly sunny weekend ahead. Now all we have to do is just hang in there through Friday as showers taper off throughout the day as the cold front slowly moves through the area and gets offshore. Temperatures will remain pretty chilly — only expect highs to top out around 50° tomorrow as the front moves by and cooler air begins filtering in.

Skies will clear Friday evening and overnight, and by Saturday, expect mostly sunny skies with high temperatures peaking around 50° as chilly high pressure moves over the region. Clear skies overnight Saturday should allow temperatures to drop to the low-to-mid-30s by Sunday morning, with freezing temperatures possible inland from the coast. The airmass will modify a little bit Sunday, and highs should warm into the mid-50s under mostly sunny skies.

Midday update: Severe threat diminishes as the wedge wins out

/ at 12:21 PM

We’re once again in the gloom with periods of heavy rain moving through the area this afternoon. This is good, though, as these clouds and rain are reinforcing the inland cold air damming wedge which, in turn, is keeping a warm front from advancing too far north into the Lowcountry. All this to say that the severe weather threat, which was never terribly high in the Charleston metro to begin with, remains rather marginal. If the warm front does sneak a little further north than projected, the risk for damaging wind gusts would come up some. The best risk for any severe storms today remains southwest of us in Georgia.

The main issue today, especially inland of 17-A, will be the potential for flooding in spots. Some areas have already received 2-3” of rain in the I-95 corridor with more to come through tomorrow. Closer to the coast, the forecast continues to call for 1-2” through tomorrow with locally higher amounts.

As always, I’ve got an eye on it. Keep an ear out in case conditions change quickly, but so far, so good.

Rain’s back with another storm chance for Thursday

We’re back into the rain on Thursday as another storm system affects the area. Expect periods of showers and storms at any time throughout the day, and be ready for the potential for a couple storms to be strong.

Clouds build back in for Wednesday with showers developing late

/ February 16, 2021 at 10:39 PM

I hope everyone enjoyed the outbreak of sunshine today! It was nice to see temperatures rebound into the mid-60s across the area with nearly cloudless skies for much of the day.

Unfortunately, our unsettled weather pattern remains in place, and today’s respite will be short-lived as clouds build back into the area during the day Wednesday, with shower chances increasing after sunset.

The sun returns for Tuesday

/ February 15, 2021 at 10:15 PM

After a stormy Monday night caps off a rather dreary weekend, Tuesday is looking a lot better with at least a brief reprieve from the rain. Clouds will be scouring out in the wake of the front swinging through, and we should be mostly sunny by afternoon. Temperatures will rise quite nicely into the low 60s, which will feel downright blazing compared to the low 40s we found ourselves stuck in over the weekend. Unfortunately, this reprieve will be short-lived as rain chances return to the forecast Wednesday. We’ll take it a day at a time, though, and enjoy tomorrow!
