PM Update: Hot Weather Continues One More Day

By Ian Livingston

Spring heat wave finale Tuesday, then cooler

* Heat Brings Weather Whiplash | Air Quality Awareness Week: Day 1 *

Day 3 of this springtime heat wave has produced more widespread readings near 90 degrees this afternoon, as south and southwest winds continue blowing warm air into the area. Dulles Airport is knocking on the door of its third consecutive record high in a row, and will have it if the mercury can hit 92. If you are among those who think it's much too early for this type of heat, fear not because cooler weather is on the way.

Tonight: Another fantastic evening is shaping up across the area as temperatures settle to near 80 around sunset. Readings will then fall to lows right around 60 in the suburbs and nearer the mid-60s in D.C.

Tomorrow (Tuesday): Tuesday will mark the final day of this early preview of summer. First we'll need to get through another day of high temperatures ranging from 85-90 across the area under mostly sunny skies. Some increase in clouds is possible late as a cold front works its way closer to the region.

See Dan Stillman's full forecast through a cooler mid and late week.

Heat Burst: As if daytime temperatures were not warm enough this weekend, something quite rare happened early Sunday. Remnants of the isolated thunderstorms that crossed over D.C. caused a heat burst in Salisbury, Md. Hourly observations show a temperature of 76 at 12:54 a.m., with some lightning noted to the west. Shortly after 1 a.m., winds picked up and temperatures started rising. By 1:54 a.m., the temperature had shot up to 87 degrees on wind gusts over 50 mph. Read more about the heat burst at and from AccuWeather.

Dulles hit 92 in between obs at 2:42, so they did tie the record. 3 in a row for that location.

As crazy as it sounds, in a couple months, we'll be killing for days like these with dewpoints in the low 50's...

The rain dance crowd is back! Channel 9 has the threat of something all this week from tomorrow evening on. Most of the threat will be relatively minimal, and tonight is one of my (rare) rainless dance evenings. Cooler weather will be somewhat of a relief and it should wash out all that pollen. Most cars in my neighborhood have a yellow-green coating. The heat wave really got our oaks going.

The frontal boundary should be in our vicinity or just to our south most of the next week.
