ROCHESTER, NY (WROC) - It's a cold start to this morning with temperatures in the 40s.  The surface high pressure that will give us a sunny day is on the move, quickly shifting east into the Atlantic. This should help get us right back into the lower 70s for highs. Humidity remains low and we get another cool night going into Friday. A weak front will develop across the Great Lakes Friday afternoon. It will threaten rain showers late, but I don't expect more than a random shower along the boundary overnight. Skies clear right back out by Saturday morning. It will be a bit cooler with highs back down into the 60s. Numbers spike back up again Sunday as another cold front pinches warm air into Western New York. This front will pack more of a punch and bring showers with a few embedded thunderstorms in the afternoon. Those storms are out by Monday, but we get even cooler from here with lows in the middle 40s and highs in the low 60s early next week.
