FORECAST IN DETAIL


Strangely, two of the biggest winter wallops of the last six months came in late October and presently - in late April. The current bout of winter-like weather brings blustery rain showers today with - yes - snow mixing in at times in high elevations to the west. Temperatures moderate some into mid-week, but two more weather systems may bring chilly rains back to region Wednesday into Thursday and over the weekend.

Today (Monday): Scattered rain showers are likely this morning (60-70% chance), mixing with and changing to snow showers in northern Fauquier, Loudoun, and Frederick counties as you go up in elevation (especially above 1,000-1,500 feet - maybe a slushy accumulation on the ridge tops). During the afternoon, showers decrease in coverage and intensity, with variable clouds and even possible peaks of sunshine. Highs range from the mid-40s in the colder north and west suburbs to around 50 elsewhere (coldest since March 6). Winds are gusty, from the northwest at 15-25 mph, gusting to 30-35 mph. Confidence: Medium-High

Tonight: Skies partially clear overnight but it remains breezy and cold. Lows range from the mid-to-upper 30s in the colder suburbs to near 40 downtown. Winds are from the west at 10-20, gusting to 25-30 mph. Confidence: Medium-High

Tomorrow (Tuesday): Partly to mostly sunny skies in the morning give way some increase in cloud cover in the afternoon. There’s a slight (20-30%) chance of a shower, but most likely it’s dry and breezy with highs 56-61. Winds are from the west at 10-20 mph. Confidence: Medium-High

Tomorrow night: Partly cloudy and cold with diminishing winds. Lows range from 35 in the colder suburbs to the low 40s downtown. Confidence: Medium-High

A LOOK AHEAD

Wednesday may be a decent day, with warmer temperatures than Monday and Tuesday and less of a breeze. It begins mostly sunny, but a disturbance coming in from the west increases clouds late. Any rain probably holds off ‘til night, with highs 64-68. Rain is likely Wednesday night, with lows near 50. Confidence: Medium

Rain showers are a good bet Thursday as several areas of lower pressure drift across a front sinking south through the region. Highs are near 60. These showers may linger into at least part of Thursday night before partial clearing late. Lows range from the low-to-mid 40s. Confidence: Medium

We should have a break from the rain on Friday as high pressure temporarily builds in from the west and northwest. It’s a little cooler than normal and breezy, with highs in the low 60s. Mostly clear Friday night and cool, with lows from the mid-30s to the mid-40s (suburbs to city). Confidence: Medium

The front that pushed south of us Thursday may back itself up over the weekend, with waves of low pressure moving along it. That means the potential for more rain and unsettled weather. Depending on exactly where the front positions itself will determine how much rain we get. If it’s right over us, substantial parts of the weekend may well be wet - especially from late Saturday into Sunday. On the other hand, if it’s to our north, it would be warmer and drier with just scattered showers. I’ll favor the drier (and warmer) forecast with highs well into the 60s and just a slight chance of showers each afternoon. But stay tuned. Confidence: Low
