Someone wake me! We got rain in Forsyth!

Mid July and most of the media out there is lamenting over the worsening drought picture for the Central US. To hear them talk, we’d be luck to see ANY rainfall before Christmas (OK, maybe I am exaggerating a bit).

Not true, at least for my little spot on planet earth near Forsyth Missouri! We had a nice steady rain this morning (July 14) that measured .44 inches. The combined with the previous rainfall comes to 1.28 inches or about half of the normal 3.15 inches that falls during a ‘normal’ July.  Now, while this will by no means break the drought, it’s still better than nothing. Only downside in my mind will be the need now to cut the grass. Something I haven’t had to do since late June!

July 2012: the first week!

After literally baking in 100 plus heat for all of the first week of July, we got some rain on the eight. Now, the new regime appears it could be both high heat coupled with high humidity! Sometimes it seems you just can’t win.

Currently, the total rainfall stands at .84 of an inch (the average is 3.15 for the month) with only a hope of more to come in the form of popup showers. Other than a very weak frontal boundary that barely moves, there has been nothing in the way of an organized front to get the atmosphere percolating once again. 

Thankfully, the water that did deign to fall (.04 on Saturday the 7^th and .80 on the 8^th), has done a lot to perk up both the lawns and the trees in my area. While it may be hard to see so early on, these three pictures show a marked improvement in the color of the grass which had been almost all brown.

One thing that appears to be for sure; the temperatures are trending upwards possibly in response to climate change. A change that may be accelerating. Each day of the first week averaged out to 104F. Even more disturbing was how warm the overnight periods were averaging at just under the 70 degree mark. The normal average has been 65 over the past thirty years! This trend, should it stick, will bode poorly.

July 8th – It was a popup shower kind of day!

A great sight to see after weeks with no rain!

Every so often all four ‘atmospheric players’ show up on the field to play their stormy games. Let me introduce each one to you:

Da Sun, da Sun! – A good storm needs lots of heat and that’s just what Old Sol provides in July. Today it was no problem to see it heat up to 100 in short order.

High Relative Humidity – This measure of the amount of moisture in the air really begins to count for something when it hits the 70 percentile range. That’s just what we had in store today as winds aloft brought in a good dose of moisture from the Gulf.

A weakening upper ridge – A strong ridge of high pressure overhead pretty much squashes any chance for a storm to develop. However, when it weakens, hot air can really rise up and bust through this invisible cap. When that happens, you’ll often see the rapid formation of cumulus nimbus clouds that can quickly punch up through the 30,000 foot mark. This action can start a tremendously powerful updraft that can suck an awesome amount of heated moisture high into the atmosphere where temperatures are far below zero. The end result – a snowstorm way up overhead. Eventually, all this refreshing coldness in the form of chilled water then descends onto the ground below. Blessed relief for all.

An approaching cool front – All frontal systems have one prominent feature, they like to stir up the atmosphere. And, when you do that, things can start happening in a much more organized way as the cool air slides underneath and then, in effect, pushes up the hot air from below. The end result, even more convection!

So, that is pretty much the setup for this date. This day (a Sunday), started out in the low seventies under clear blue skies. However, if you were to look out over a valley, you’d see a lot of haze – (that’d be all that moisture I was talking about). And, those clear skies were not to last very long, as moist and heated air packets began to rise ever higher into the atmosphere. Once they got up to about a mile high, the colder air at that level began to condense them into cumulus and other cloud formations. Things were becoming more and more unstable!

By 3:30 PM, the heat outside had built up to the 100 degree mark (this is becoming normal) and there were cumulus nimbus clouds all around Forsyth Missouri. Unfortunately, not a single rain producer was overhead. In the distance, I could occasionally hear thunder. Outside, the street by my house was becoming increasingly littered with dead leaves as water stressed trees shed their leaves. A kind of early fall was going on.

When the showers finally came at 6:30 PM it was the perfect deal. A long three hour fall that dropped .80 inches onto a parched and burned earth. And, while this day did not break the drought, at least it signaled a change. Now, let's see what tomorrow brings...

Got Drought?

Rains finally come back to Forsyth Mo. on July the 7th!

It was really nice to hear thunder again and those rain drops were heaven sent, I think. This change in the guard occurred on the afternoon of July the 7^th when I spied rain falling, abet sporadically, outside my window at about 1:30 in the afternoon. The cells were coming in from the northeast and while no one shower offered up that much, it was still nice to see. It’s been quite some time (back in mid June) since we’ve had any measurable water falling from the sky. And, while I don’t expect this day to put any sort of dent into what’s become a worsening drought, it was better than a sharp stick in the eye!

The question now is what will happen next. Are we going to see a return to a ‘normal’ July or will this pattern of heat with little to no rain persist?

Early July 2012 heat wave!

Another few days of one hundred degree plus days to go, That’s according to the National Weather Service that is calling for a cool front to invade the mid west sometime during the weekend of July the 7^th.  This chart shows the trend over the past week or so:

 Outside, just about every living plant or tree is now showing signs if both heat stress combined with a lack of adequate moisture. Rainfall, across this region has been all but non existent. Lawns everywhere have gone dormant and even local gardens that are being watered on a regular basis are looking sickly. Currently to only survivors in my raised beds have been a few tomatoes and peppers. Everything else is pretty much gone!

June 2012 versus 2000

In looking way back to June at the turn of the millennium, it’s instructive to note the differences in temperature. Here is a copy of the original temperatures I recorded for June 2000.

 

Note that the average for the month was about 71F. Next, take a look at June 2012. Wow, a full seven degrees warmer, on average.
