The tropical flow ahead of a sloth-like cold front in the Midwest and a big high pressure area in the northwest Atlantic team up to bring in the season’s warmest and most humid air, thus far.  The combination of heat and humidity make it feel like the lower half of the 90s this afternoon.  Scattered showers and storms this afternoon or evening may offer relief, but a backdoor cool front arriving tomorrow really cuts into temperatures, slicing them by about 10-15 degrees and putting the brakes on this trend towards summer weather.

Temperatures could rebound briefly into the lower 80s on Thursday when the main front finally forces its way through the area with some dousing rains.  Ultimately, we set up for a cooler, drier, and sunnier weekend that could reasonably compete for one of the best this spring to date.

Today (Tuesday):  Partly to sometimes mostly sunny skies, warmer and a bit more humid as highs work up into the middle to upper 80s this afternoon. A few spots may even touch 90.  Dew points in the 60s make peak temperatures feel like they are in the lower 90s or maybe briefly hotter.  Increased cloud cover and late afternoon into evening showers and thunderstorms could (30 percent chance) offer some temperature oscillations.  Winds are light, mostly from the west, but may shift to come from the east later in the day.  Confidence: Medium

Tonight: A backdoor cool front edges down through the area.   It offers a risk of scattered evening showers and thunderstorms, but otherwise, we’ll aim for cloudy skies with light breezes from the east as lows dip down through the 60s.  Dew points hold in the lower 60s, so the air starts to feel somewhat more humid, meaning our air conditioning may need to keep working a bit longer from the daytime hours.   Confidence: Medium-High

Tomorrow (Wednesday): Partly to mostly cloudy and not nearly as warm with temperatures reaching back up into the middle to upper 70s with a few spots south and southwest of the city perhaps hitting 80F or just inside the low 80s.  Winds are light and from the east at 5 to 10 mph, and we still can’t rule out the risk of widely scattered afternoon to evening showers with perhaps a rumble of thunder.  Confidence: Medium-High

Tomorrow night: Partly to mostly cloudy conditions as temperatures slip back into the 60s.  We could yet find a scattered shower or thunderstorm as breezes continue to blow lightly mainly from the easterly and southeasterly direction.   Confidence: Medium-High


Thursday is a bit trickier as we get a quick burst of warmer winds ahead of the bigger cold front arriving from the Midwest.  Skies are partly cloudy, but we could break into the sun at times, allowing temperatures to pop into the lower to middle 80s for afternoon highs.  We also have a shot at afternoon showers and storms, but they seem to still be more scattered vs. widespread.  Thursday night brings in the heavier stuff just ahead of the cold front with showers and storms likely especially toward midnight and into the early morning hours.  Lows in the lower to middle 60s.   Confidence: Medium

Friday features the stormiest weather of the week as the cold front whips through the region.  Showers and thunderstorms could be heavy at times during the morning through early afternoon, with some reduction by later in the afternoon toward evening, but still partly to mostly cloudy skies.  Highs should only manage the 70s due to rains and clouds.  This should be enough precipitation to push May back to above normal overall levels.  Friday night could see some lingering showers toward evening, but lows drop to cooler levels overnight ranging from the middle to upper 50s.  Confidence: Medium

The weekend looks much improved with comfortable highs in the lower 70s and cool lows in the 50s.  Skies could start both days more on the sunny side, but then shift to partly sunny in the afternoon with the slight risk of an afternoon shower or sprinkle due to some upper level instability.  Most of the weekend should be dry and comfortable with temperatures generally below normal for middle May.  Confidence: Medium-High
