With Cristobal staying far offshore and just whipping up coastal wave activity, we continue to benefit from broad high pressure offering warming temperatures, but keeping humidity relatively low for another day.  Temperatures edge higher into the middle 80s today and then upper 80s to low 90s tomorrow as a warmer wind starts to blow.  Humidity edges up a little bit, but still not too terrible in comparison to what we can see in August.

A weak cool front pushes through early Thursday, sending humidity back down.  Highs in the 80s with relatively low humidity and plentiful sunshine ends our final week of meteorological summer.  The Labor Day weekend features some added heat and humidity with daily chances of thunderstorms (higher on Sunday-Monday vs. Saturday).

Today (Tuesday): High pressure holds in place with our air mass gradually warming.  Sun-filled skies prevail with highs edging higher up through the middle 80s.  Humidity is ever-so-slightly higher than yesterday, but still relatively low.  Light and variable winds.  I really wanted to peg this as a Nice Day, but some areas may get out of the Nice Day range by sneaking above 85 degrees during the afternoon.  Confidence: High

Tonight: Clear skies should prevail as lows drop down into the upper 50s in the outer suburbs to the middle 60s in the city; still a fairly comfortable situation with light breezes.  Confidence: High

Tomorrow (Wednesday): Our hottest day of the week with mostly sunny skies and temperatures surging into the upper 80s and low 90s by afternoon.  Dew points edging up into the middle 60s offering some moderate humidity feeling, so this is the least comfortable day of the week also.  Winds start to come from the southwest at 5 to 10 mph as our recent pleasant high pressure exits into the ocean and we await the next one for late week.   Confidence: Medium-High

Tomorrow night: Partly cloudy as a cool front approaches the region.  Lows only dip into the middle 60s to near 70 right in the city as humidity stays a bit more elevated.  This looks like it will be a dry cold front with winds shifting overnight to set up a nicer Thursday and Friday.  Confidence: Medium-High


Thursday and Friday feature a new air mass that is warm (middle to upper 80s for highs), but not humid (low to edge of moderate humidity) with mostly sunny skies.  Thursday night’s lows are comfortable with low to mid-60s.  Friday night should be partly cloudy with lows in the mid-to-upper 60s.  Confidence: Medium-High

The holiday weekend seems determined to give us a last-minute taste of typical summer heat and humidity in the Mid-Atlantic as we shift toward the start of meteorological autumn.  Partly sunny skies on Saturday shift toward partly or mostly cloudy skies on Sunday and Monday.  Highs range from the middle to upper 80s to near 90 with lows Saturday and Sunday night dropping down to the upper 60s to low 70s.  Probability of scattered showers and storms are about 30% on Saturday afternoon/evening and then up to 40% on Sunday and Monday.  Confidence: Medium
