PM Update: Hot Weather Continues One More Day

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.

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.
