FORECAST IN DETAIL

Was it something we said? Temperatures today through the weekend are more typical of February than late March. And then there is that nasty issue of frigid rain possibly mixing with or changing to snow early Sunday. Only a die hard snow lover could hope for that. In any event, a grassy coating is possible which would look pretty since it greened up last week.

Snow Potential Index: 3 (↑) - There are several model runs supporting enough snow to cover grassy surfaces very early Sunday morning. This requires threading the needle, too far north and the storm brings only rain, too far south and the moisture is pulled away.

Today (Thursday): Only the early commuters should have to deal with constant windshield wiper needs. The rest of us should see no more than light showers or sprinkles ending around mid-morning. It would not surprise me to see a slushy flake or two mix in especially in the western suburbs. And areas with some elevation out toward Front Royal could get a grassy coating. Even after the showers end, the clouds hang on and worse, the winds from the north at 10-20 mph are a chill factor. Highs only manage to reach the mid-to-upper 40s. Confidence: Medium

Tonight: Clouds begin to break up after sunset and winds gradually die down overnight. This allows temperatures to head south in a hurry. Lows should fall to the mid-20s to lower 30s (downtown). Protect your tender plants! More details on that in my garden blog post later today. Confidence: Medium-High

Keep reading for the forecast through early next week...

Tomorrow (Friday): Any lingering clouds should dissipate quickly as high pressure builds across the area. The colder air surging across the area is impressive given the stronger springtime sun with highs only in the mid-to-upper 40s. Winds from the north at 10-15 mph bring out the jackets. Confidence: Medium-High

Tomorrow night: The chill is in the air from the outset of this evening. Winds are nearly calm. Lows should end up in the upper 20s to low 30s. The only thing that may keep readings from not falling lower is that some clouds could build back in after midnight. Confidence: Medium-High

A LOOK AHEAD

Saturday is just not a great day. Readings in the 30s in the morning only make the mid-to-upper 40s yet again. A far cry from the normal which is now around 60. Clouds are gradually thickening and lowering through the day as well. The evening is uneventful with readings headed back into the 30s by midnight. There could be a few sprinkles after midnight possibly mixing with or changing to snow by daybreak as lows fall to the low-to-mid 30s. Confidence: Low-Medium

Sunday dawns with the threat of light snow or a rain/snow mix for a few hours. If the track of the storm trends too far north, precipitation may be mostly rain. Or, if it tracks south, little precipitation would fall period. In any event, snow is not likely to amount to more than a light coating on grassy areas due to the limited amount of moisture. Clouds remain stubbornly in place all afternoon. Temperatures barely climb with highs only in the upper 30s to lower 40s. Clouds depart overnight and lows reach the upper 20s to lower 30s. Confidence: Low

Monday at least starts out mostly sunny. However, clouds may increase later in the day and highs once again are held back reaching the mid-to-upper 40s. Confidence: Low-Medium
