PM Update: Beautiful summer weather persists

By Ian Livingston

High heat on the horizon for the 4th and beyond

July is off to a fine start as we get treated to another below average day across the region. Temperatures reaching the upper 70s and lower 80s this afternoon are running a good 5 to 10 degrees below the typical high this time of year. We've got one more of these glorious days to go before temperatures rise back to near normal on Saturday and then probably way back above normal for the 4th and into next week.

Through Tonight: Mostly clear skies and temperatures falling through the 70s create a perfect evening for outdoor activities. Last night, winds kept temperatures from reaching the full cool potential in many spots and a light breeze could do so again tonight. Nonetheless, lows as cool as the mid-50s are possible in the suburbs while lower 60s are more likely in the city.

Tomorrow (Friday): Hopefully you're starting the long weekend early so you can enjoy one more day of cooler than normal temperatures. Mostly sunny skies and low humidity ensure that afternoon highs ranging from near 80 and into the low 80s feel mighty fine.

Tropics: Hurricane Alex made landfall in northern Mexico late yesterday (see landfall loop) in a fairly remote area along the coast. The system was a Category 2 storm with sustained winds around 105 mph. Alex was the first June hurricane since 1995 and the strongest June hurricane since 1966. The central pressure fell all the way to 947mb, which typically translates to a Category 3 system, but winds were not able to reach such levels.

This pattern reminds me a lot of July 1988. On July 1 we got as much of an arctic airmass as DC can get in midsummer: DCA reached 77 with dewpoints around 40 - just like today - after an overnight low of an incredible 54! The rest of the month (and the summer), however, was scorchingly hot, featuring 21 consecutive 90-degree days to tie the 1980 record.

Since we've just begun a new meteorological "year", all of the previous season's snowfall data has been taken down from the daily NWS DCA, BWI, and IAD "Past Weather Information" pages. The data was up there this a.m., so that was quick.

As noted in previous posts, it will be interesting to see by how much the annual snowfall totals for these locations are adjusted.

Or, if the NWS goes with 15.2" again this year for DCA (and 18.2" for BWI and 21.2" for IAD), it will mean they didn't factor in last season's totals into the annual averages.

And, oy vey, will we snowophiles start yelling!

I hope you both have your windows open!

@JerryFloyd1

I too am interested to see what the new climate normals for snow will be, but I think they usually wait about two years after the climate period to update them.

Don't hold me to that, as I was too young to be paying attention last time around, but I think the last update was in 2002.
