Mount Holly AFD on the long range-
Overview... Synoptically, a consistent upper level pattern will be in place for the long term. Broad, strong ridging remains centered over the Intermountain West, with troughing over New England. This places our region in the belt of mid-level northwesterly flow between these features. Surface flow will also favor a westerly direction, which will mostly keep the oppressively high humidity away from the region. However, the temperatures themselves remain near to above average, due to the effects of the upstream ridging and efficient surface heating thanks to some downsloping effects with the westerly flow. Regarding rain chances, next week should feature plenty of dry hours, but will probably not be without its shower and storm chances as well. Unlike what we`ve seen most of the month, this pattern of relatively lower dew points and faster flow aloft is not very conducive to heavy rain and flash flooding. However, with that faster mid-level flow, the passage of multiple weak frontal systems and/or fast-moving mid-level impulses is possible. This should continue to bring at least sporadic opportunities for convection. This flow regime is also a classic example of what`s sometimes referred to as the "ring of fire". Severe, long-lived mesoscale convective systems can occasionally propagate from the Midwest to the East Coast in these patterns, often occurring with poor predictability more than a day or two out. With this pattern looking to be locked in place for awhile, this will be something to keep an eye on.
