Back to a wintry feel the next few days

After a cold, blustery Tuesday where the high only reached 33º, readings surged 16 degrees to 49º Wednesday afternoon under strengthening March sunshine as the city enjoyed its warmest day in more than a week. However, a reversal of fortune will send the mercury tumbling back toward 40º the next few days as an upper-level disturbance settling into the Midwest brings clouds and periods of snow showers to the area. Little improvement is expected until early next week as the upper-level system slowly moves out, allowing surface winds to shift to the south and sending temperatures back into the 50s.
Tuesday’s snowstorm, which left a deep snow cover downstate and across portions of the Plains and southern Midwest, is long gone—but cold air moving southward in its wake will send temperatures plunging to levels near or below freezing across much of the southern U.S. in areas from Texas to the Carolinas this morning and again tonight.
