Mostly Cloudy, Cooler

Despite low clouds associated with an upper level disturbance, cold air advection was strong enough to drop temperatures into the upper 40s this morning. These low clouds may be a nuisance for much of the day and will keep temperatures much cooler than normal. The culprit of these clouds is an upper air disturbance located over the Ohio River Valley that has essentially become cut off from the main flow. This upper low is meandering very slowly, but it should lift far enough northeast by tonight for skies to clear. With mostly cloudy skies this afternoon and cold air advection, I think the high will only top out around 61. Winds may be a bit breezy this afternoon with an increased pressure gradient. Clouds should clear out tonight for a short time, but an increase in low level moisture early tomorrow morning may lead to the development of more low clouds. With this in mind, I'll forecast a low of 42 tomorrow morning.
