Forecast: Another April shower soaking today

Slow improvement Wed. then nicer Thurs. & Fri.

NatCast: Showers may challenge game

Update 1:00 p.m.: Showers will move back into the region over the next hour or two from south to north.

Update 11:25 a.m.: A bit of a dry slot has worked its way into the region allowing skies to partially clear. However, an upper level low to the southwest will trigger showers and thunderstorms later this afternoon. The sunshine we’re getting now may destabilize the atmosphere some, and with cold air moving in aloft, any storms that develop may produce hail and mix down some strong winds. There is a slight risk of strong to severe storms, especially east and southeast of I-95.

FORECAST IN DETAIL

Just like last week, we manage one nice day (and Monday of all days!) before the weather comes crashing down to the cool, wet, and dreary side. This business lingers into tonight and maybe tomorrow morning before nicer weather finally returns for Thursday and Friday. Unfortunately, we’re still in a variable spring pattern which means we can’t expect the good weather to persist into the weekend. Another storm system arrives Friday night and, if we’re lucky, it leaves by Sunday afternoon.

Today (Tuesday): Low pressure has developed along an approaching cold front currently en-route to the D.C. metro region. The storm system is moving excruciatingly slow and amazingly is not expected to really leave our locale until tomorrow morning. Therefore, expect periods of showers and t’storms today with cloudy skies. Temperatures hold steady early and then falling though the 60s. Winds from the east and north at 5-10 mph. Most spots should see at least quarter inch of rain, with a few spots over 0.5”, mainly north of town. Confidence: Medium

Tonight:Evening rush hour showers are likely before activity slowly decreases overnight. Temperatures drop down into the mid-to-upper 40s in most areas. Confidence: Medium

Tomorrow (Wednesday): Morning clouds and a stray shower are possible with some partly cloudy afternoon conditions. Temperatures only manage to reach the low-to-mid 60s, but breezy conditions from the north at sometimes 15-20 mph make it feel a bit more brisk. Confidence: Medium-High

Tomorrow night: Partly cloudy and cool with lows in the low-to-mid 40s. If we clear enough, outlying areas could dip into the upper 30s. Confidence: Medium-High

A LOOK AHEAD

Thursday finds us back on the weather upswing with mostly sunny skies and temperatures rebounding into the upper 60s and low 70s. Mostly clear skies will accompany low temperatures in the mid-to-upper 40s on Thursday night. Confidence: Medium

Friday should be a decent day, but there is some degree of risk to this forecast. Clouds could encroach by late afternoon into the evening with a chance of evening showers or storms. My feeling right now is that most of the day is good with highs in the low 70s again before evening rush hour showers and storms. More showers and storms are likely Friday night with lows in the 50s. Confidence: Low-Medium

In all honesty, the weekend looks wretched. Perhaps the forecast will improve as we get closer, but at this point, Saturday looks rainy and cool with highs only in the cool 50s. More showers Saturday night (lows in 40s) with variable clouds on Sunday with 50s to possibly low 60s. I’m somewhat hopeful that we’ll get some sunshine sneaking into the picture at least by Sunday afternoon. Confidence: Low-Medium
