Showers Monday Into Early Tuesday

Coastal Low Brings Raw Rainy Weather Later This Week

Today was certainly a good example of what happens when a warm front comes to a grinding halt. To the north and east it has been a raw cloudy rainy day and temperatures settled in the 40s. To the south of the warm front which stalled in Southern New Jersey and Southern Pennsylvania, temperatures climbed to the upper 60s to mid 70s and this evening we are seeing some thunderstorms that have popped up in Central Pennsylvania.

That boundary is going to start sinking southward tonight and that leaves our area in a rather gloomy place for tonight and Monday with on and off rain or showers. This is going to impact temperatures with most highs Monday just into the 50s. Some places along the coast will probably sit in the mid to upper 40s most of the time.

This certainly is payback for the 4 nice days we had last week. Seldom do we see such a nice streak in April. This week will be more typical of April where gloom and doom conditions take hold. Clouds on the satellite arc from the coast back to the Great Lakes spiraling around and upper low sitting back in Ohio this evening.

That upper low should finally pass by to our south and east early Tuesday and that could lead to some improvement. Rain will be gone by Tuesday morning and clouds should give way to sunshine rather quickly. Temperatures Tuesday should be back into the upper 50s and lower 60s. However there is a problem as the upper air map below shows.

The traffic jam in the Atlantic continues and there is a stronger upper low behind the lead system. The upper low in the Great Lakes will dive southeastward to the Delaware Coast and then inch slowly offshore. While we catch a break Tuesday into early Wednesday, clouds will start to return later Wednesday. Highs will be in the upper 50s and lower 60s. Rain could arrive late in the day and then continue Wednesday night and Thursday.

This time of year cold air is dwindling but the strong upper low will be providing some of its own and it could play out as wet snow in higher elevations in Northern Pennsylvania and Upstate NY. A cold rain is likely elsewhere with temperatures just in the 40s with even some 30s well inland in those elevated areas.

The low is slow moving and it may take until the weekend before we see some genuine improvement. The good news here is that the rain is much needed in much of the Northeast and Northern Mid Atlantic states. 2 to 3 inches of cumulative rain is possible this week from these two systems. We are going into a new moon phase with peak tides in a few days so we need to watch for the possibility of some coastal flooding this week.  Last week’s weather was an anomaly. This week will be much more typical of April.
