Texas is located north-northeast of Mexico and our prevailing winds typically are from the south-southwest (except when a cool/cold front comes in and then the winds are from the north). And because of this we are covered from late Spring into early Autumn by a heat cap coming up from the south-southwest. It is the heat cap that prevents us from getting thunderstorms or rain of any kind during the summer/early fall, the stronger the heat cap the less chance of rain. This Spring as soon as the last good cold front was through with us in February and had moved on to the northeast to become one of really heavy snow storms up there, the heat cap arrived-- almost 3 months earlier than normal and with a vengeance. There are only two things that will break a heat cap.....a really strong cold front from the north/northwest or a ground level temperature of 100 to 110 depending on how thick the heat cap is at any time. Some parts of the cap are thinner and the storms can happen in those areas of the state, that's why so much of the rain has been east and south of me last year and some this year. January 9th was the last time my immediate area got rain. I really don't believe that the barely measurable 1/8th inch last week counts as rain. But early this morning a strong cool front came through and broke the blasted thing (it's weaker at night), 84 days aka 12 weeks aka 5 days short of three months, my yard got rain!!!! There was thunder, lightning, more thunder and more lightning, heavy rain, light rain, heavy rain again more 'storm' than we have seen here in about a year and this morning there is 1.25 inches of precious rain in my rain gauge. My plants are drinking deeply from Mother's Natures best watering system and enjoying the hits of nitrogen from the lightning. I won't be working outside but I also won't be turning on the AC again for a few days either since the temperature won't be in the 90's this week.
Toni, the same storm system hit us about 7:30 this morning with strong winds, a 20 degree drop in temperature, and some rain. We didn't get as much as you, but we're grateful for whatever we got! I checked our rainwater collection tanks, and they are up an inch or two. With no measurable rain in two months, each of our 250 gal. tanks were about half full. I've been watering transplants and the vegetable garden out of them, and that slowly depletes our store of water. Let's hope we get more rain, and this time, a gentle rain!
I envy both of you!,..we could do with less rain here,..every time i want to go walk the dogs,..go boating or fishing,..i must first check,..IS it raining,..or WILL it rain shortly,..i wish i could do a deal with you,..you give me a good amount of your dry sunny weather,..i will give you as much rain as you need,
If you could figure out a way to send about 5 inches a month to each of us that would be great. Personally I would be willing to trade you the whole month of August for it.
Is a 'heat cap' a local term for persistent hot air that won't move? I am unfamiliar with the term. Jerry
I don't know about where you are but down here the Heat Cap is literally a cap of hot air that has come up from Mexico and is sitting on top of us several thousand feet up. Pretty much through the middle of the state from Mexico to the Red River, sometimes narrower than other times and sometimes reaching up into Oklahoma. It prevents weak cold/cool fronts from coming this far south and when storm clouds pass over us you can see the flattened bottom of the clouds. Then when the storm clouds reach an area where the Cap is weak or non-existent then they build up and rain. And lower level rain clouds will hit the Cap and totally fall apart and are no more.
That cold front began to show up here (between Houston & Beaumont) around 2pm. Not alot of rain, so far... not even an 1/8th of an inch. But the temps have been dropping steadily. They are saying it could get down to 41F by morning. But the highs will get up to the mid 70s. And again down to 40s on Wednesday morning. Can still hear a bit of thunder rumbling off in the distance. So there's hope more of the rain will come this way. Toni and Jane... so glad you all finally got some rain up there!
