Significant snowfall in the southern Rockies

Folks who live in parts of Massachusetts, Connecticut, southeastern New York, and Rhode Island are waking up to a cover of snow this morning. Snow will taper off quickly this morning and will be over by the late morning hours. With the departure of the storm system, our attention will shift to the November chill that has settled into the region. Temperatures will be cold through the weekend with highs ranging from near 30 northern Maine to the 50s in Virginia. Lows will range from teens and a few single digits northern New York and northern interior New England to the 20s in the Mid-Atlantic. Temperatures will gradually trend toward average in the coming week. Aside from the departing storm and the impending chill, the Northeast will be dry and quiet for some time as high pressure takes control.



Most of the Southeast will be dry this weekend but persistent easterly winds will bring showers into eastern Florida and coastal South Carolina/Georgia. Meanwhile, an active pattern over the Southwest will keep much of Texas and Oklahoma unsettled right through midweek. With cold air initially in place, the first disturbance sweeping out across the high Plains Saturday will bring snow to much of the Texas and Oklahoma Panhandles with showers elsewhere across the southern Plains. Temperatures Saturday will be 5 to 25 degrees below average. It appears that much of Oklahoma and Texas damp and dreary through at least Wednesday with temperatures very slowly trending back toward average.



Much of the Midwest will undergo a dry period for awhile. The only exceptions will be some showers in southwest Kansas today, a few showers from Kansas to Wisconsin on Monday and a few showers around the Great Lakes Tuesday. The rest of the region will remain dry as high pressure maintains control. Temperatures will be 5 to 15 degrees above average from the northern half of the Plains into the western Great Lakes and trending toward average elsewhere.



As a trough of low pressure becomes anchored over the Southwest, a few disturbances will rotate eastward around the trough. One disturbance will swing from the Southwest into the high Plains today with locally heavy snow for the southern Rockies (maybe as much as 1 to 2 feet in the highest elevations of the San Juans and Sangre de Cristos) and 4 to 8 inches out into the high plains of northeast New Mexico. Lighter showers and mountain snow will linger over the remainder of the Four Corners' states. Meanwhile, a new storm will split apart at the West Coast as high pressure aloft still protects southwest Canada and the Northwest. The new disturbance with very limited moisture will slide down the California coast into Baja and northern Mexico over the weekend and then prolong showers especially in New Mexico through midweek. Late Sunday and Monday, a wetter Pacific system will come into Washington, western Oregon and northwest California but fizzle over the interior. Elsewhere, look for some morning fog on Saturday over parts of Washington, Oregon and Idaho, especially in the river valleys. Cities in Oregon like Portland, Salem and Eugene are under an air stagnation advisory into Saturday.
