Judging by the day’s weather and the forecast for tomorrow, you might mistake it for late April. But no, it’s late January. After temperatures soared to near 70 today, we make a similar run Wednesday. And the spring-like day may end with a bang with a round of gusty showers and possible thunderstorms after dark.
Through Tonight: It certainly doesn’t feel like winter. Overnight lows will be well above average highs. Under partly cloudy skies, we only drop into the upper 40s and low 50s. A little fog could develop late.
Wednesday: For much of the day, it’s variably cloudy and very mild. Highs are similar to today, cresting between 65 and 70. The record of 77 from 2002 should be safe though. The wind from the south spiriting in the mild air is pretty strong, at 10-20 mph. We could (30 percent chance) see a shower or thundershower before dark, but the main risk is between 8 p.m. and just after midnight.
Per Ian Livingston’s earlier post, heavy rain and strong, gusty winds are possible in tomorrow evening’s showers/storms. The National Weather Service Storm Prediction Center even says the region has a slight risk of severe thunderstorms.
Coastal flood watch Wednesday afternoon/night: Wednesday’s strong southerly winds will push water up the Chesapeake Bay and Tidal Potomac, resulting in the potential for moderate coastal flooding. Tides may be about 2-3 feet above normal, including in Alexandria and Georgetown. More info.
Severe weather in lower Misssissippi and Tennessee Valleys: Tornado watches stretch from northeast Texas through the Ozarks and into southwest Illinois well into the evening. A powerful cold front is likely to produce a “signficant severe weather event” extending from that region into the western Tennessee Valley overnight. The National Weather Service Storm Prediction Center cautions a few strong tornadoes and numerous damaging wind events are possible.
