Another cool, clear morning is underway with below average temps and below normal dew point readings. A bit of fog was being detected mainly in Southern Illinois at 3 am. In terms of today's weather...no significant changes are expected locally although temps may notch up a degree or two this afternoon as we lose the light northerly winds. However....a large area of very wet weather is moving southeastward through the central and southern plains this morning. Although it appears that the rain itself will remain just to our south and west (as close as western Arkansas) we'll likely get some cloud cover sneaking in from the west today....which may act to counter any significant warming trend. Bottom line: another very nice late July day with below average temps and humidity levels. A few more clouds may keep it slightly less cool tonight but lows should still be in the M50s to L60s.
Longer term....the upper trough that pushed the cool, dry air into the area a couple days ago will be going away....so we should expect a gradual increase in temps and humidity levels....but only slowly. By the weekend we should see highs in the M80s to U80s...and by early next week we'll have daytime highs near 90 with more humidity again. In terms of appreciable rainfall...as noted there may be some heavy rain to our west and southwest the next day or two but only small chances of showers are expected locally...especially Friday and Saturday with a very weak upper trough crossing the area. The next significant widespread rainfall may not occur until sometime later next week when models indicate a stronger upper trough and cold front toward next Thursday or Friday.
