Many areas today reached 56 degrees for a daily maximum. Let’s figure tomorrow we cool down twenty degrees and that gives us a high of around 36 degrees as a cold front passes this evening. On Friday, we do at least ten degrees better and therefore I have 46 for a high. On Saturday, we could do another ten degrees better and I am forecasting 56 degrees. On Sunday, ahead of a cold front, we could briefly reach 66 degrees. Should the rain be heavier or should the cold front be ahead of schedule, we would only rise into the upper fifties. On Monday, 46 should do it with colder air behind the front. So it is no mistake in the 5-Day that I have 36, 46, 56, 66, and 46.
A warm front will lift through the region on Friday. It will be responsible for increasing clouds, but there should not be any well-defined showers. The bulk of the rain in the extended forecast will be in response to the strong cold front on Sunday. Waves of low pressure may ride along the front, bringing periods of heavy rain and thunderstorms. Another inch or two of rain seems like a plausible scenario. With an area of high pressure slowly moving in the Atlantic, the front may slowly move out. This could be a setup for flooding if we have a front stall across our region with continual disturbances moving along it. Right now, confidence is not high enough on the timing to begin to forecast possible flooding, but these types of systems are notorious for ending up being heavy rain makers. By this time, our waterways could also be able to take on two or three inches of rain before flooding begins.
