MESONET TICKER ... MESONET TICKER ... MESONET TICKER ... MESONET TICKER ... July 23, 2020 July 23, 2020 July 23, 2020 July 23, 2020 Going south http://ticker.mesonet.org/archive/20200723/hanna.png Oh boy, here we go. Tropical Depression 8, possibly soon to be Tropical Storm Hanna, is now churning its way through the Gulf of Mexico headed towards the Texas Gulf Coast. Here's another view of what's going on from the National Hurricane Center, with forecast strength thrown in as well. http://ticker.mesonet.org/archive/20200723/hanna-forecast-cone.png The forecast cone clearly has the remnants of Hanna traveling straight across south Texas into northern Mexico. Where it goes from there is the key. Does it continue to the west until it goes *POOF* after getting disrupted by the high terrain, or does it curve back to the northeast into our area? Or, does it miss us altogether but allow some of that rich Gulf moisture to be pulled into the High Plains region? I'm betting on that latter scenario. There is also the possibility of a cold front entering the area as we get into early next week, so with that enhanced tropical moisture, maybe...just maybe, we can get some decent rains out in the panhandles of Texas and Oklahoma. http://ticker.mesonet.org/archive/20200723/nws-amarillo-hanna-moisture.png A lot has to happen to get that magic to occur, but hey, it's better than it looked a month ago, right? And so does the drought picture out that way. Check out the improvements in the Panhandle and parts of northern Oklahoma. Unfortunately, we also see plenty of reasons for concern in west central and southwestern Oklahoma, which saw a surge of severe-to-extreme drought over the last month. http://ticker.mesonet.org/archive/20200723/20200721_OK_trd.png http://ticker.mesonet.org/archive/20200723/1month-DM-change.png After a quick improvement in soil moisture across the state, we suddenly see those areas of improvement replaced by worsening conditions. I called it whack-a-drought" yesterday, as we see improving impacts in the north replaced by worsening conditions to the south. http://ticker.mesonet.org/archive/20200723/USDA-soil-moisture.png http://ticker.mesonet.org/archive/20200723/soil.moisture.2inch.png http://ticker.mesonet.org/archive/20200723/soil.moisture.10inch.png http://ticker.mesonet.org/archive/20200723/1week-soil.moisture.change.png The 7-day rain forecast again shows the inundations expected from the impact of Tropical Storm Hanna, and the possibility of some of that moisture surging to the north and northwest, strengthening the monsoonal flow over the inter- mountain region. http://ticker.mesonet.org/archive/20200723/7day-rain-forecast.gif But all in all, we're in a rather mild summer pattern. Temperatures should remain close to if not below normal, especially with that front approaching next week. http://ticker.mesonet.org/archive/20200723/nws-norman-7day-temps.png With the humid conditions we have, and summer heat, AND the lack of that strong high pressure dome directly over us, we should see pulse thunderstorms go up and rain a ton and then die out here and there over the next 7 days and maybe even longer. Whether you get rain depends on the vagaries of Mother Nature and where those storms go up, because they ain't gonna move much once they do.
