Going for the gold: National hits 90+ for 67th time

* Cool air set to arrive: Full Forecast | NatCast | UnitedCast *

Washington, D.C. has reached 90 or higher on 66 67 days in 2010, the second tied for the most on record. The previous record holder was 67 from 1980 as we've stated an untold number of times on this blog.

The forecast high today is around 89 -- oh, so close. We think there's a 40% chance Reagan National (DCA, D.C.'s "official" observing station) makes 90.

Track today's temperature each hour right here:

Evening update: Today's official high was 93 at DCA . Dulles also reached 93, breaking the previous record of 92 from 1970. It was the fourth straight day Dulles tied or broke a record high.

4:00 p.m.: As if to put an exclamation point on matching the 90+ record, it's up to 93 (the record for the date is 95 set in 1930).

2:05 p.m.: We've done it! An off-hour observation of 91 has been recorded in the last 6 hours at National according to the 2 p.m. update.

2 p.m.: 88 with an east wind still at National. Some local stations (College Park) are now touching 90. Looking good to get there?

1 p.m.: Now up to 86. This is at least going to be close.

12 p.m.: 83 again. Temp held steady probably due to influence of front. Yesterday we were at 87 at noon. We need a wind from the west to kick in to give us a bump.

11 a.m.: It's 83. Surprisingly, yesterday at this time it was just 82 on its way up to 99. But the cold front moving through the region at this very time will put the brakes on the mercury's ascent this afternoon. The question is: can sunshine and a downsloping (warming) wind from the west get us those seven degrees?
