FORECAST IN DETAIL

It took long enough but spring has finally sprung around here!  We lose yesterday’s cloudless blue skies, but in a trade-off we get more warmth.  That warmth continues to pump in as we head into the work week and high pressure builds over the western Atlantic. Other than some clouds and a stray shower chance here and there, the forecast period looks warm and pleasant, with highs into the 70s tomorrow and perhaps close to 80 by midweek.

nice_dayToday (Sunday): The day may end up with its fair share of clouds. But partly sunny skies, a warming air mass, and winds breezing from the south at 10-20 mph are enough to push afternoon highs to the mid-to-upper 60s (perhaps a bit cooler at National Airport with a breeze off the water). Just a 20% chance of a passing shower. Yeah, maybe more clouds than technically meets the criteria for a Nice Day stamp, but  the welcome warmth has us feeling lenient. Confidence: Medium-High

Tonight: Skies are partly to mostly cloudy as a weak cold front approaches and I won’t totally rule out a stray sprinkle or brief shower (20% chance).  With the added moisture in the air, temperatures won’t plummet after dark like they have recently, with overnight lows staying in the upper 40s to low 50s. Confidence: High

Tomorrow (Monday): High pressure takes hold off the East Coast, and the clockwise circulation around it means a surge of even warmer air from the south. Skies still see a fair amount of clouds, but partial sun helps afternoon highs all the way to the mid-to-upper 70s with breezes around 10 mph from the south. With a frontal boundary nearby, we’ll keep a 20% chance of a shower in the forecast. Confidence: Medium-High

Tomorrow night: A nearly stationary front remains set up to the north of the region. Most of the associated showers should stay north, but can’t rule out a stray one sinking south into our area. Otherwise, we’re partly to mostly cloudy with overnight lows that could be warmer than recent highs, only dropping into the mid-to-upper 50s. Confidence: Medium-High

A LOOK AHEAD

On Tuesday, that pesky front to our north is still close enough to cause a shower concern.  Right now, it looks like most rain gets hung up around the MD/PA border and north, leaving us enjoying partly sunny skies and highs spiking to the mid-to-upper 70s. But there’s some chance it sags a bit to the south, which would bring an increased chance of showers, thicker clouds and highs held in check in the mid-60s to mid-70s. Still can’t rule out a shower Tuesday night, with very mild lows in the mid-50s to low 60s. Confidence: Medium

If all goes as planned, we’ll find ourselves Wednesday with the front to the north lifting away, and an approaching cold front to the west still too far to have much influence.  That would spell partly to mostly sunny skies and highs in the mid-70s to near 80. But timing of fronts is tricky this far out, so more clouds, a shower chance and a bit cooler temperatures are still in play at this point.  Confidence: Low-Medium
