Showery (Isolated Rumble of Thunder) & Unseasonably ChillyOctober 5th, 2012 at 1:38 pm by Chad Evans under Chad's WLFI Weather Blog
Today is the coldest early October afternoon since 1987. As of 1:40 p.m., it is just 46 degrees after 50s this morning. Our high today occurred at midnight with 57.
Showers (with potential of isolated rumble of thunder) continue to pass with anafrontal boundary slowly sinking southward well ahead of the rainfall. Anafront is a surface front that has most of the rainfall behind the front, since the mid & upper winds are parallelling the surface front.
The heat & warmth has been everywhere but here in October (after record hot, dry weather in the Plains & West in September & cooler-than-normal & wetter-than-normal in the East), but now below-normal temperatures are overspreading the entire eastern half of the U.S. with record heat in the West.
So far, we have not been able to shake below-normal temperatures & wetter weather (except for yesterday), but model data is insistant of the upper ridge building eastward or at least more zonal flow developing after October 13.
In terms of rainfall, it looks above-normal until October 13, then drier. We will see if October will indeed be warmer-than-normal & drier-than-normal as predicted. So, far we are not there in our viewing area. The warm, dry weather in October has been the greatest in the Plains from southern Canada to Texas to the West Coast, so far.
