A stalled frontal boundary along the Mason-Dixon Line and the southward push of lower dewpoints came to a grinding halt before pushing into our neighborhood. That’s why it remained hot and humid all weekend. That same frontal boundary is in the process of slowly pushing back northward as a warm front. The bottom line is that we are in store for more sticky weather around here tonight and tomorrow. With high dewpoints, a front nearby and an upper level arriving from the west, the result will be an unsettled period tonight and tomorrow with fairly numerous and showers and t-storms. Our main concern with showers and thunderstorms that develop is the threat of locally flooding downpours.

By tomorrow evening, drier air will be moving in from the northwest, behind a weak surface cool front. That will put a quick end to any residual showers and t-storms around in the evening. We are also expecting a nice drop in dew points on Wednesday with a northwesterly flow. That will probably be our most comfortable air mass that we have had all month! Odds favor it staying dry and comfortable on Thursday, however at some point the pattern will turn “dirtier” with higher dewpoints and more moisture returning.
