July 22, 2014 July 22, 2014 July 22, 2014 July 22, 2014 A Time To Sweat http://ticker.mesonet.org/archive/20140722/a.time.to.sweat.jpg Have you ever watched "A Time To Kill" and noticed how everybody is dripping sweat in almost every scene like they've been on a treadmill for 2 hours? That's what I assume Mississippi is like from June through August. Well, all our praise and glory over last week's record-cold weather has done gone and put us in the middle of an old fashioned Mississippi style summer heat wave, courtesy of our least favorite author, Mother Nature. Look at yesterday's temperatures, and remember them fondly, because it'll get worse (today and tomorrow) before it gets slightly better (Thursday, sorta). http://ticker.mesonet.org/archive/20140722/yesterdays-highs.png http://ticker.mesonet.org/archive/20140722/yesterdays-high-heat.indices.png Those heat indices across the western half of the state are worthy of a heat advisory, so that's exactly what we have now, courtesy of the NWS offices in Tulsa and Norman. Tulsa County has even got the coveted "Excessive Heat WARNING." Ain't they lucky? http://ticker.mesonet.org/archive/20140722/NWS-advisory-map.png An excessive heat warning means heat indices in the 105-110 degrees range. A heat advisory means heat indices around 105 degrees. Don't be shocked if values are above that 105 degrees mark today even in western Oklahoma. Here's what we can expect for the next couple of days, courtesy of the NWS folks. http://ticker.mesonet.org/archive/20140722/nws-amarillo.jpg http://ticker.mesonet.org/archive/20140722/nws-norman1.jpg http://ticker.mesonet.org/archive/20140722/nws-norman2.jpg http://ticker.mesonet.org/archive/20140722/nws-tulsa.png http://ticker.mesonet.org/archive/20140722/todays-highs.png http://ticker.mesonet.org/archive/20140722/wednesdays-highs.png We could see a brief and slight cool-down on Thursday as a weak cold front slides into the state. Don't expect last week's cool weather, however. More like merely bringing us down to seasonal averages at best. And then the hottest days appear to be hitting us this weekend. No idea if the heat indices will be as high, but there is a lot of moisture to be evaporated by old Sol. http://ticker.mesonet.org/archive/20140722/thursdays-highs.png http://ticker.mesonet.org/archive/20140722/fridays-highs.png http://ticker.mesonet.org/archive/20140722/saturdays-highs.png As long as this supply holds out, there will be humidity. And that's only in addition to what is being brought up from the Gulf on those southerly winds. http://ticker.mesonet.org/archive/20140722/topsoil-moisture.png http://ticker.mesonet.org/archive/20140722/10inch-soilmoisture.png But what a change in less than a week, eh? Take our station in Hooker, for instance. It reached a HIGH TEMPERATURE of 63 degrees on July 17th, and yesterday it rose to 103 degrees out that way. That's like going from the middle of March to well above July's average temperature in 5 days. http://ticker.mesonet.org/archive/20140718/july17-highs.png It does make for an interesting temperature trace over that period (the top graph on this meteogram). It's a heat tsunami! http://ticker.mesonet.org/archive/20140722/Hooker.7day-meteogram.png But never fear. It does look like we'll see a somewhat similar pattern from last week build for next week as well. Not quite as cold, probably, but another big cool trough across the eastern U.S. and a hot ridge across the west. We'll be somewhere in between where the nicer temps and a bit of moisture are (hopefully). Remember, these maps show probabilities, not magnitudes, of possible temperature and precip anomalies. http://ticker.mesonet.org/archive/20140722/jul27-31-precip-outlook.gif http://ticker.mesonet.org/archive/20140722/jul27-31-temp-outlook.gif The rain is just starting to show up on the 7-day map, although some of this is from Thursday's chances in the far east and west. http://ticker.mesonet.org/archive/20140722/7day-rainfall-forecast.gif Maybe next week, we'll be starring in "A Time To Use An Umbrella."
