Holy Dry Air Batman!

Looks like some moist air is heading North on Monday. Keep dumping the water glasses, it seems to be working.

It's a dry one alright, but it's still kind Aprill and so we may see a change in the next few weeks

Some ridiculously dry obs from this afternoon (dewpoint depressions of 95 and 97 F):

Site: Sundown (WTM)
Time: 0535PM
Temp: 86
Dewpoint: -9
RH: 2%
Winds: SW 24G33

Site: Wink (ASOS)
Temp: 95
Dewpoint: -2
RH: 2%
Winds: W24G32

Note the drought conditions (Drought Monitor) across most of the area, and the CPC forecasts drought to persist across western TX and eastern NM.

I'll set the bar with this from Las Vegas:

ON JULY 2ND LAS VEGAS ASOS RECORDED A DEW POINT DEPRESSION OF 120F AND A RELATIVE HUMIDITY VALUE OF 1 PERCENT (ALTHOUGH THIS IS NOT AN OFFICIAL RECORD...THIS IS THE GREATEST DEW POINT DEPRESSION IN RECENT MEMORY).

Wow ... that's impressive.

I just spilled a glass of water and it evaporated before it hit the floor it's so dry!

... with a Td depression of 120ºF, it would be more like, "hey, who drank my water!"

Very impressive DPD's. While nowhere near as extreme, New York and New Jersey have been seeing very dry air with RH values in the 15-30% range during the day. We have not seen rain in over 1 week and most of this week will be dry aslo. There have been many large brush and forest fires over the past 5 days. It is getting bad here as well as out in the Plains.

One thing is for certain...added moisture from the ground and evapotranspiration won't be helping with any severe weather setups in the near future.

I'm not a fan of predictions or comparisons, but if you ask me what this year reminds me of, it's 2004.

I suggested back in early March (looking at major teleconnections and synoptic patturns at the previous 3 months) that this year looks very comparable to 2000... with a lot of troughing over the Great Lakes and Eastern U.S. causing veered low-level flow associated with nearly every short-wave over the Southern Plains. Lot of tornadoes (or at least a modest amount) occurred over the Southeastern U.S. in the early spring that year with a majority of the Plains tornadoes occurring in late spring over Nebraska, Iowa, and Illinois. There might be a couple big days in the Southern Plains in May and June, but I'm willing to bet the Central/Northern Plains will see a brunt of the action in May and June.

This reminds me of one of Dave Hoadley's classics.

Heh, yeah no doubt. If you read this tonight, take a look around the Childress, TX area at the surface obs. One of those kinds of drylines there. 46 degree dewpoint change across Childress/Hardeman counties.

Trying an image post...

(edit) Hard to see, but dewpoint is 60 at Goodlett?, and 14 at Childress, about 15-20 miles or so.

Is this correct? 93/-29

 

[David Drummond]

I would imagine not, given the readings around that station.

 

[Scott Weberpal]

Wow, after seeing tha I'm starting to doubt the -11 Td, probably closer to -5, if that.

 

[David Drummond]

Either way you look at it, it's as dry as a dinosaur fart out here.
