A big dip in the jet stream is sending a rare July cold front our way with storms likely this afternoon, followed by some unusually mild temperatures for this time of year. Storm coverage increases late this afternoon across Central Arkansas, especially after about 4 PM. Some storms may produce gutsy winds, possible hail, very heavy rainfall and frequent lightning. A severe thunderstorm watch is in effect for a large part of Central Arkansas through 8 PM. The timing of storm development will mean some potentially wet and stormy conditions for the evening commute. Storms will push through the State during the evening hours, and push into Southern Arkansas by later tonight. Cooler air moves in behind the front for Tuesday, with high temperatures only in the 70s and 80s across the State. Lows Tuesday night and Wednesday morning will drop into the lower 60s with 50s North making for an unusually comfortable morning for mid-July. Temperatures will remain well below normal through the middle of the week with highs remaining about 10 to 15 degrees below normal for this time of year. A warm front begins to push back North for Thursday and Friday bringing rain and some storms back into picture.
