AREA FORECAST DISCUSSION

Weather Synopsis:
A developing low pressure system will pass through the Mid- Atlantic tonight and then offshore by Saturday. This low pressure system will be followed by high pressure building into the region through early next week. A strong frontal system then looks to impact the area during the middle to end of next week.

Near Term:
THROUGH SATURDAY - High pressure over the area weakens as it slides offshore. Several shortwaves will pass through the region through this evening, and this will keep skies cloudy. Cloud bases may lift this evening, and could even scatter out a bit.

Weak low pressure currently over Nebraska and Oklahoma will track east through the Midwest and Ohio Valley tonight, and will be near the Appalachians after midnight tonight. This low will slowly work its way through the Mid-Atlantic and Delmarva Peninsula Saturday morning. The low will then be some 200 miles south and east of Nantucket Island by Saturday afternoon. Weak upper level troughiness with strong shortwave energy passes through the region late in the day as surface high pressure builds in from the west.

Rain develops over the area late tonight and continues through Saturday morning. Most of the rain will taper off around midday, though some lingering rain may persist over the coastal areas as the low departs. Conditions then improve late. Overall, can expect 1/4 to 1/2 inch QPF throughout, though less than 1/4 inch north of I-78 and closer to 1/2 inch over Delmarva.

Fairly mild for this time of the year with lows in the low to mid 40s tonight, and then in the low to mid 50s on Saturday.

Short Term:
SATURDAY NIGHT THROUGH MONDAY - A high pressure system continues to build in from the south and west Saturday night with cooler drier air in place. Lows Saturday night will be in the mid 20s to mid 30s with a mostly to partly clear sky.

Our high pressure system sticks around for Sunday which leads to a dry day with a mostly clear sky for many with some more clouds as you head north but these areas still look to be mainly partly cloudy. Highs are in the mid 40s to mid 50s. A weak cold front moves through Sunday night but does not result in much aside from a light passing shower. Any precip potential looks pretty limited.

On Monday, our surface high remains in place which keeps the day dry and mainly clear. Some clouds start to filter in by the later afternoon hours from the west ahead of our next system. Highs on Monday are in the mid 40s to mid 50s.

Long Term:
MONDAY NIGHT THROUGH FRIDAY - We stay dry Monday night with increasing clouds across the area. Our high pressure system exits to the east. There are then two low pressure systems that we see bring some precip to the area. One moves into the Great Lakes Region and then eventually into Canada while the other moves out of the Tennessee River Valley area and into the Mid-Atlantic region. What this means is that we start to warm up ahead of the systems with multiple rounds of rain which is followed by two cold fronts.

For the more specific details, we start to see warm air filter in Tuesday into Wednesday. Highs on Tuesday are mainly in the low 50s to low 60s. By Wednesday, highs are mainly in the low to mid 60s. As the warm moist air filters in, we also see increasing rain filling in by midday. The best coverage of the rain looks to be Tuesday night where PoPs are around 70%. Our first cold front with the low moving through the Mid-Atlantic region moves through Wednesday which continues to lead to periods of rain or rain showers. The cold front with the low in Canada then passes through Wednesday night into Thursday morning which also continues to keep periods of rain or rain showers going through Wednesday night. Cold air filters in behind the cold fronts and results in highs for Thanksgiving in the low 40s to low 50s. One key note is that given this being towards the end of the long term period, there is still some uncertainty with the timing of the systems and their cold fronts. Some deterministic guidance does look to keep rain around on Thanksgiving with the systems being slower. Regardless of the timing of the cold fronts, behind them is notable cold air advection.
