Thursday’s Outlook: Temperature Swings and Storms

Relief continues for the snow wearied…

While I certainly can’t rule out the possibility of snow falling in small quantities, it’s definitely not the star of the forecast for Southern New England at any point during this period. In fact several days of above normal temperatures could continue much needed relief as mid atlantic states recover and continue to melt down their snowpacks.

Upper Level discussion: Some weak ridging has built into the eastern US today. This will erode away with an amplifying trough approaching from the west through tomorrow. A strong southern branch jet stream sits to our south for the early part of the period. The best dynamics for cyclone development from it evolve pretty far offshore tomorrow (just south and east of the benchmark). A weakening shortwave transits the great lakes region this weekend while some ridging is reintroduced in the east. A larger trough enters in the west next week out ahead of which, ridging builds in the east.

Surface discussion: A frontal system approaches northern new england tomorrow associated with a weakening clipper system. Low pressure develops offshore near or just south and east of the benchmark and quickly tracks towards the Canadian maritimes while intensifying. A cold front associated with a low transiting central canada approaches on Monday night. Then, Low pressure developing near the rockies early Monday tracks up towards the great lakes by early Wednesday. Expect well above normal temperatures into mid-week due to warm advection out ahead of the low. The low’s associated cold front finally comes through late week and a return to colder temperatures is forecast by the end of the period.
