WEATHER BLOG: Warm Up Ahead

On the weather map early Sunday morning high pressure was exiting the Mid Atlantic Coast while low pressure was crossing the northern Great Lakes. A warm front attached to the low was bringing showers to upstate New York. These showers will stay well north of the region as they move east to New England. At the same time a cold front with spotty showers was attached to the low and was crossing the western Great Lakes. High clouds streaming out ahead of the cold front will pass overhead and bring dim sunshine, but at the same time increasing winds from the southwest will transport milder air into the area as temps rise into the 60s. The weakening cold front will pass through the region Sunday evening, but all of the cool air and moisture are lifting north into Canada, so conditions will remain mild and dry Sunday and Monday. Some sunshine and winds from the west downsloping off the Appalachians will also promote mild weather as temperatures reach the low 70s.

At mid-week a series of weak low pressure zones will pass along a quasi stationary front stretching from the central Plains to the Northeast. The first low that will pass to our north on Tuesday will bring the chance for a brief shower Monday night and on Tuesday (mainly northern suburbs), though many places will stay dry. It will remain quite mild with highs in the mid or upper 70s. In the wake of this low, the stationary front will remain north of the area. A weak jet stream disturbance passing over this boundary may bring some showers to places north of the city early on Wednesday, otherwise it will be dry and warm. The summery weather regime will linger into Thursday as a storm and low pressure center move northeast from the Ohio Valley. A cold front attendant to the low will pass through the area overnight and on Friday, bringing heavy rain and a good chance for a gusty thunderstorm.

Cooler and drier air will return for the weekend.
