(KFVS) - A surface high over the Great Lakes will give us light northeasterly winds over the next couple days....blowing in some slightly lower dew points/humidity with time. By afternoon dew points look to be below 70 over our northern counties, but will still be in the low to mid 70s in southern counties. The moisture across the south, combined with the weak front, will likely lead to a few afternoon thunderstorms from the Bootheel east into KY and TN by afternoon and evening...while northern counties stay mostly sunny and dry. Thursday and Friday look to be mostly sunny and seasonably hot, but just slightly less humid except perhaps for the Bootheel and NE Arkansas which will likely be about the same.
By the weekend humidity levels will be increasing once again....so it will be a very hot and humid weekend. Shower and storm chances begin to notch upward again by Sunday and into early next week, though...as a pattern change begins to develop. This will be a national-scale shift...with our recent high pressure area retrograding westward....allowing light northwest flow to develop over the eastern half of the country. This should bring a slightly cooler and less humid pattern...but could expose us to more severe weather systems moving thru from NW to SE.
