    8:55 p.m. update: Latest data suggests tomorrow is probably *not* our first 90-degree day of the year. Despite some sun, there should be enough clouds to keep highs to around the mid-80s at best. Also, there’s a chance we could wake up to a leftover shower or t’storm from the batch currently moving east through West Virginia (see radar), in addition to the s hower/storm threat later in the day.

    12:40 p.m. update: Line of showers approaching from the west on track to move through area over next 2-3 hours. So far the showers are light to moderate with no lightning, but that could change.

    Acceptable morning w/ some sun. More humid p.m. 80s (& a t’storm?) remind us of the summer to come.

    Prepare to get damp over the next several days - either via increased shower and thunderstorm chances, or by the increased mugginess in the air that will make you sweat more and more. The year’s first 90-degree day may be close at hand as summer-like heat accompanies the higher humidity, especially starting tomorrow. And as you might expect, that combination has the potential to spark isolated to scattered storms, mainly in the afternoons into evenings.

    Today (Sunday): Not quite the gem that yesterday was. It’s more of a summery feel with partly sunny skies, noticeably higher humidity, and temperatures rising toward highs at least in the low-to-mid 80s. Upper 80s might be within reach if we see more afternoon sun than I currently anticipate. We’ve got a slight (10%) chance of showers and thunderstorms starting early-to-mid afternoon, increasing to 30% late afternoon into evening. The Nats and O’s at Camden Yards (1:35 p.m.) probably avoid any rain, but you might take a small umbrella if you’re risk-averse. Confidence: Medium

    Probability: 30%
    Coverage: Isolated to scattered
    Most Likely Timing: Mainly after 2 p.m.

    Tonight: Some of us might get a heavy evening downpour as thunderstorm chances stay around 30%, then diminish overnight. Mostly cloudy skies and muggy air should prevail, even in areas that remain dry or just see a light shower or two skirt by. Lows just before sunrise are mild - in the low-to-mid 60s area-wide (luckily I just got my A/C repaired!) Confidence: Medium

    When might we hit 90? Keep reading for the forecast through midweek...

    Tomorrow (Monday): Perhaps our first 90-degree day of the year? Not out of the question, but far from a sure thing. Either way it’s plenty humid with partly sunny skies, afternoon breezes picking up from the south, and highs somewhere in the mid-80s to near 90. The afternoon into evening brings a 30-40% chance of showers and thunderstorms. Could make for some commuting headaches here and there. Confidence: Low-Medium

    Tomorrow night: Any showers or storms quickly die down. Lows remain warm & sticky, most likely in the mid-to-upper 60s. Confidence: Low-Medium


    Tuesday and Wednesday continue at least partly sunny, very warm and fairly humid. Highs should range in the mid-80s to near 90 again with an increasingly familiar 30% chance of mainly afternoon/evening showers or storms. Plan to take it easy outside, ok? It’s been a while since our bodies have felt this kind of heat and humidity - they’ll need time to acclimate. Confidence: Low-Medium
