Thundershowers should pay most of us a visit today and boy can my yard use it. The immediate DC area is on the verge of a drought and as my gardening blog later today will note, the street trees are suffering. If only we didn’t have to worry about a few severe storms. Weekend outdoor events should fare better as storms will be more isolated. Temperatures sneak back up to more typical levels but humidity only slowly climbs and remains manageable for whoever takes over the grill for Dad. I do worry about the U.S. Open golfers getting done before thundershowers return on Sunday.
Today (Thursday): Only high clouds are expected to start the day as blow off from yesterday’s storms in the Midwest pass overhead. As temperatures warm, thundershowers will start to pop up west of the city and drift into town during the afternoon (70% chance). The atmosphere should be unstable enough to foster isolated severe thunderstorms capable of high winds and hail. Keep checking in here for the latest as the day progresses. Rain amounts should be mostly in the quarter to half inch range. Except in storms, winds blow from the south at 5-15 mph. Highs occur early afternoon in the mid-to-upper 70s. Confidence: Medium-High
Most Likely Timing: noon to 9 p.m.
Tonight: A couple of waves of thundershowers (60% chance) are still possible, but once the sun sets things should quickly settle down. Breezes from the south are only 5 to 10 mph and readings in the lower 70s in the evening should be delightful once the showers are out of the way. Lows settle into the low-to-mid 60s. Confidence: Medium-High

Tomorrow (Friday): Skies start out mostly clear but there is still an unstable atmosphere over our head so look for midday thundershowers to pop up fairly vigorously as we add some heat to the mix. Yes, seasonable temperatures will be making a return with highs in the low-to-mid 80s. The humidity is still only half heartedly trying to return, thank goodness. At least half of the area should see a shower between noon and 6 p.m. Breezes come gently from the west unless you are in the middle of a shower. Fortunately, severe potential is much lower. Confidence: Medium
Tomorrow night: Skies clear out and temperatures quickly slip back into the 70s in the evening. This provides a great view of the rising, not quite full, but oh so large moon in the west. Calm winds are welcome for dining alfresco. Overnight lows slip to the lower 60s suburbs to upper 60s downtown. Confidence: Medium
Saturday offers up every excuse to get out and enjoy the innumerable outdoor events in the area. The sun is high in the sky and with clear skies readings climb rapidly into the upper 80s to lower 90s. That should not be as hard to take as you might think given the moderate humidity levels we should still be enjoying. However, they are likely to start climbing in the evening as a warm front approaches that could trigger a late day or evening storm (20-30% chance). Lows should hold up in the upper 60s to lower 70s. Confidence: Medium
Father’s Day (Sunday) is a pretty typical early summer day with highs rising to the upper 80s to lower 90s and humidity more tangible. The warm front over our heads is likely to focus some afternoon and evening thunderstorms on the area so keep Dad away from the grill! There is a 50-60% chance of storms in the area and locally heavy downpours are a possibility. Evening readings hold in the upper 70s and lower 80s except cooler in areas of the stronger showers. Lows should reach the upper 60s to lower 70s. Confidence: Medium
Monday, the last day of astronomical spring, looks every bit like summer to most of us with mostly sunny skies, a good dose of humidity and highs in the low-to-mid 90s. One wonders what summer will bring?! Confidence: Medium
