PM Update: Remaining hot and humid on Tuesday; Iowa tornadoes

Temperature Map

Temperatures: Latest D.C. area temperature map. See interactive map on our Weather Wall.

We tacked on another day with highs 90 or greater in D.C., but we’re still running a little behind in that count compared to average. Keep in mind, the city typically sees about two weeks of such days in July alone. A day (or weekend!) without, should be seen as a bit of a present perhaps. No presents coming tomorrow…

Through Tonight: Skies remain partly to mostly clear through the night with just a very outside shot of a passing shower or t’shower. A light south/southwest wind keeps humidity high. With the high humidity and slow-to-evacuate warmth of today, plan on lows only making the near 70 to mid-70s range.

Tomorrow (Tuesday): Payback for our stunning 4th of July weekend continues, but it’s really not too terrible for this time in July. Humidity is moderate to high as afternoon readings head mainly for the low-to-mid 90s. We’ll need to keep an eye to the west and northwest late to see if any storms roll this way. Odds are fairly low (30-40%) but any storm could be strong to severe.

Iowa tornadoes: Several tornadoes touched down in central Iowa yesterday. Interestingly enough, they occurred in an area not under a severe thunderstorm or tornado watch.

One of at least 11 tornadoes reported in Iowa on Sunday loomed over Reinbeck that evening. National Weather Service employees and Iowa residents reported seeing funnel clouds in several areas of the state. (Facebook/Shawn Murphy)

Most of the tornadoes appeared to be weak, if also rather photogenic. Surveys continue today to determine strength, and at least one has been rated an EF1 by NWS Des Moines.
