High pressure will remain in control of our weather today, and mostly sunny skies will be the result. This high will remain in control through Thursday before merging with another area of high pressure to our southeast over the Atlantic. With a deep trough over the eastern United States, cooler than normal temperatures can be expected again on Wednesday, and then moderating some Thursday and Friday with the return flow becoming more southerly/southwesterly. Meanwhile, the cold front boundary that moved though our area on Monday will retrograde northward back toward the NJ and DE coastline later in the week. With that in mind, as well as an increase in dewpoints and to some extent instability, we introduced widely scattered chances of mid to late day thunderstorms beginning with Friday. The convection Friday will be very disorganized, and no severe weather is expected. The weekend then gets a bit tricky – the front offshore will become quasi-stationary, and weak low pressure is expected to traverse the stalled boundary. Model guidance is all over the place with these features. Timing and exact location of this boundary are difficult to pinpoint, as is the timing of low pressure moving along that boundary, with a modeled range as early as Saturday early morning to Sunday early morning. As such, we kept the chances of showers and storms on both days, with slight weight given to Saturday, but will fine tune in the coming days. The stalled front will then dissipate early next week and partly cloudy skies return for Monday along with a trend toward warmer than average temperatures as the new work week rolls in.
