While much of the nation will close October out with fairly cold temperatures, a sliver of warmth will hug the East Coast, keeping temperatures closer to late September/early October normals for the work week. Upper-level disturbances will keep the weather rather unsettled as well, with rain chances Tuesday-Friday before a cold front ushers fall back into the picture for the weekend.
Another cold front will be moving through the area on Tuesday, bringing along some more fall-like weather for Wednesday and beyond. Before it passes, though, we’ll see temperatures spike into the mid-80s with scattered thunderstorms in the area. A few thunderstorms could produce strong, gusty winds in the late afternoon/early evening hours. Be alert to possible warnings.
The front is expected to clear the area around sunset or a little later. Temperatures will cool down nicely behind said front, bottoming out in the low 50s for Wednesday morning.
After the wettest day since Dorian, a ridge of high pressure will usher in fall weather for a few days, with the potential for the first 40° readings of the season Thursday and Friday mornings. Then, a slug of tropical moisture will bring in another solid rain chance late this weekend into next week.
Sunday will finish with a little more warmth than we’ve had the last couple days as high pressure slips offshore and a front stalls out nearby. Clouds will be on the increase throughout the day, but rainfall is expected to hold off until overnight. Highs will top out in the mid-80s; with dewpoints in the 60s, this will feel a little warmer and more humid than we felt on Saturday.
The second half of 2019 will get off to a fairly hot start, with heat indices running in the low 100s each afternoon. Scattered thunderstorms will provide relief, particularly later in the week. (Must be July in Charleston.)
We will make another run at the century mark today, with a decent chance of at least tying the all-time May high temperature record set yesterday (100°). In fact, this morning’s NWS forecast has the airport breaking that record once again today. While there is no Heat Advisory today as heat indices will remain below 105° (pre-July 1 threshold), it will still be plenty hot (even at the beaches, where low 90s are possible) and you should still keep heat safety precautions in mind when observing Memorial Day today.
Today is day one of a potentially long-duration, early-season heat wave that will continue into at least next week. Record heat is forecast today, with a high of 98° expected. If this verifies, this would break the record of 97° set in 1953. Air conditioning is best today (and for the next several days), but if you must be outside, take frequent breaks, drink lots of water, and seek shade regularly.
Today is the “calm before the warm” as the pattern begins to kick into place for a significant, long-duration heat wave starting tomorrow. (More on that later today.) A shower or storm can’t be ruled out early today, but as the ridge builds, clouds will decrease. The vast majority of us remain bone dry. Temperatures will range from the upper 80s in the Charleston metro to the low 90s closer to I-95.
We’ve got another dry and seasonably warm spring day ahead. Temperatures will top out in the low 80s under partly cloudy skies; onshore flow will aid the seabreeze in punching through the area this afternoon, which will keep temperatures in check. A shower or two can’t be totally ruled out along and ahead of the seabreeze this afternoon, mainly inland from the coast.
Drought continues over the Lowcountry as we head into the first full week of May. Some of you got some decent rainfall this weekend, but for many of us, just a few showers fell. (I got a grand total of 0.05″ on Saturday and Sunday, the first measurable rainfall since April 20.) Moderate drought conditions continue, with mostly dry weather (save for the potential for a thunderstorm this afternoon) expected through Wednesday.
