Heat Wave #2: UPDATE

                   High center will shift a bit eastward, but overall conditions won't change much in Texoma this week.

 UPDATE: Mon 19 July 2010 / 3:10p.m.

Daytime highs will ease back a degree or two as the week wears on, but relative humidity values will remain quite high. This means only a subtle change in the daily "feels like" temperatures. A few showers could show up later in the week as the large high aloft shifts eastward (map).

The bottom line: What has been a mostly hotter than average summer will continue that trend into the last part of July.

 

==================================================================

Expect very hot weather like we experienced during much of June.

A large mid-level high (map) will meander over the south and southwestern United States from now into next week. This will provide typical mid-summer weather: sunny to partly cloudy days, and very hot conditions.

Given the high soil moisture content and southerly surface flow, it's going to be very humid for the next few days, and probably into the weekend as Gulf inflow continues.

The only potential cooling would be if a wave were develop in the clockwise flow around the high's perimeter. At this time, there is no indication this is going to happen.

Heat Index values will likely run in the 105-110 range each afternoon, so please pace yourself and drink plenty of fluids if you're out in the heat!

 

UPDATE: Friday 16 July 2010 / 10:40a.m.

Well, there's really no change to my original forecast of several days ago.

Uncomfortably hot and humid weather will continue well into the new week with daytime Heat Index values exceeding 110 degrees in some areas. This is a more stressful condition that we saw with our June heat wave; in that one, the air was somewhat drier.

So while it was plenty hot, it was easier for the body to cool off than we're finding during this July blast 'o heat. If you use common sense and basic summer heat safety you should be OK.

It would be a good idea to keep an extra caring eye on elderly relatives without air conditioning.

Take Care...Steve
