DAYS 1-5 (JUNE 22-26)<\/p>\n\n\n\n
I don’t have many adjustments to make to yesterday’s discussion and forecast. On the large scale, we remain in a transitional but somewhat repeating pattern. Transient Rex block (high pressure eastern Canada \/ US Northeast with low pressure to the south southwest of this region) moves into a transient omega where the trough to our southwest becomes the eastern member of a pair of upper level lows (Ohio Valley and West Coast to Rockies initially). But this pattern will be transitional, as in not generally stationary upper features but ones that progress eastward, albeit not at the same speeds. The easternmost low takes its time drifting eastward through this coming weekend while the one further west is moving along more swiftly, and the reason the “omega” setup is short-lived is because the western upper low catches up and overtakes the eastern one in the Northeast by early next week. What sensible weather to we get as a result of all of this. In summary: An unsettled overall pattern lacking any real heat, but not lacking humidity. We start today again with some areas of stratus, most of it set to dissipate as the sun rises higher into the sky, but look for increasing high to mid level clouds from the south north. Why? A warm front will approach today into Friday and likely take until late Friday to get full through the region. I’m not expecting widespread rainfall from this feature, as initially it will battle dry air, and some previous model forecasts of a rainy Thursday afternoon\/evening will not come to fruition. Some sprinkle\/rain may work into the South Coast and a few areas south of I-90 by this evening, but not enough to cancel any outdoor plans you have. Some patchy rain moves up through the region tonight and when we get to Friday it’s more a domination by clouds and not so much by rain, with just a few passing showers possible as the warm front works its way across the region. If there are any heavier showers Friday they are more likely to occur in the western reaches of the WHW forecast area (toward the Connecticut Valley). Despite the inability to really heat up as the warm front passes due to the abundant cloud cover, you will notice the humidity spike up. And the higher humidity is to be with us through the coming weekend and Monday as well. During this time, we’ll see the upper low to our west meander a bit and then edge eastward, making it close to the region by Sunday, while the second low will be playing catch up and reach the Great Lakes \/ Midwest by Monday. Along with the aforementioned higher humidity we’ll also see shower and thunderstorm chances this weekend and Monday, but I suspect Saturday’s activity will be more on the isolated to scattered side, favoring Cape Cod early in the day and interior areas mostly well west and northwest of Boston from the afternoon through evening, so Saturday itself may not really be that bad a day with warmer temperatures and the chance for more sun, as long as you don’t mind the humidity increase. Shower and thunderstorm chances increase Sunday and Monday, but there will be a diurnal component to them, with most numerous activity likely reserved for the afternoon and early evening hours. And while it will certainly not be raining all the time any of these days, any rainfall that occurs has the potential to be heavy.<\/p>\n\n\n\n

DAYS 6-10 (JUNE 27 – JULY 1)<\/p>\n\n\n\n
Upper level low pressure traverses the region from west to east into the middle of next week with shower and thunderstorm chances and high humidity through June 28, then as a weak ridge moves in behind the departing low expect a drying trend and slightly warmer conditions June 29 through July 1.<\/p>\n\n\n\n
DAYS 11-15 (JULY 2-6)<\/p>\n\n\n\n
While this forecast is still low confidence, the trend is similar to the thinking of yesterday. A weak block may reappear with high pressure north and low pressure south, but displaced a little more so the high is further east and low further southwest. Placement and oscillation of features would determine day to day weather but the overall idea for now is a little drier and temperatures that run near to slightly below normal with a tendency for more large scale flow off the Atlantic instead of a land breeze. This would prevent major heat through the holiday period.<\/p>\n","protected":false},"excerpt":{"rendered":"
