Good Morning, The weekend brought much of the Eastern Region nice weather, and yesterday was a bit warmer than Saturday in a few places… In many others, there was little or no temperature change between the two days… The humidity was also quite low, with dew point temperatures no higher than the 40s… Early this morning, we have a high pressure system on the current surface map that is destined to drift off the mid-Atlantic and Northeast coasts during the next 36 hours… The return flow on the back side of this zone of high pressure will result in a southwesterly wind flow… This will be responsible for continuing the recent warmer weather trend, and the humidity will be moderately higher tomorrow and Wednesday… Its getting to be that time of year when words like “muggy” are going to be more common in our vocabulary, and when we’re confronted with a series of three consecutive days or more when the temperature will either peak in the 80s or the upper 70s, it only seems fitting… We’re going to have an uptick in the humidity tomorrow, which may just be enough to trigger showers and some heavier thunderstorms… At this time, we feel that the biggest threat later tomorrow and tomorrow night in thunderstorms that occur east of the Appalachians will be some hard downpours - but not necessarily strong wind gusts or hail… The precipitable water values will be on the rise (which is typical in an increasingly humid air mass), and some of the thunderstorms could move fairly slowly… This will raise the threat for localized flooding, but there also could be many locations that gain less than a quarter of an inch, when all is said and done… An unsettled weather pattern is expected to continue during midweek, and we’re inclined to make some adjustments to our temperature forecasts for Wednesday and Thursday, based on the idea that there will be plenty of clouds around both days, as well as a couple of showers and a thunderstorm or two… Based on recent runs of the various global models, we’re convinced that a rather slow-moving cool front is finally going to reach the Eastern Seaboard late on Thursday afternoon or early Thursday night… Then, some drier air will be able to filter into the Northeast and portions of the mid-Atlantic states on Friday… As long as a bubble of high pressure located in the Great Lakes region becomes the dominant feature on Friday and Saturday, then the weather around here should be dry, and temperatures will be close to the seasonal averages… Have a good day!!
