Sorry for the late start. I had basketball on the brain for much of the day today. Off to South Carolina!
At 1156PM, ET, Columbia was reporting a temperature of 57 with clear skies. An enormous ridge was dominating the eastern two thirds of the country, though there we was an undercutting trough tapping into the warm air, setting off a few thunderstorms in the Mississippi Valley.
The low over the center of the country will get entrained with the mean flow and pulled to the northeast. With an overriding flow pattern stronger than the low, it will rapidly be sheared apart. The return flow boundary is presently along the Mississippi River, and the associated moisture will continue to be drawn eastward as the parent low is sheared apart. The shower activity will weaken considerably, and strong thunderstorms are not expected, but as the weak boundary pushes eastward, there is still a shot for some light rain on Tuesday afternoon.
Tomorrow – Sunny, High 74, Low 49
Tuesday – Increasing clouds, with a chance of late rain, High 78, Low 54
TWC: Tomorrow – Partly cloudy skies during the morning hours will become overcast in the afternoon (late rain) High 71, Low 49
Tuesday – A few showers early with isolated thunderstorms developing later High 78, Low 56
AW: Tomorrow – Partly sunny High 71, Low 44
Tuesday – Partly sunny and very warm with a shower or thunderstorm around High 78, Low 52
NWS: Tomorrow – Mostly cloudy (rain late) High 70, Low 49
Tuesday – A chance of showers, with thunderstorms also possible after 2pm. Mostly cloudy, High 77, Low 54
WB: Tomorrow – Mostly cloudy (rain late), High 70, Low 47
Tuesday – Mostly cloudy with a chance of showers. A slight chance of thunderstorms in the afternoon High 77, Low 54
So it appears there is some thought of a bit of rain overnight Monday as well. Not buyin’ it! Satellite shows a classic comma shaped pattern with that low in the center of the country.
