At mid-levels, a low will move across far northern New England this

evening, as northwest flow remains in place from the Appalachians

northwestward into the northern Rockies. At the surface, a cold

front will move southward across the central and southern Plains

into the mid Mississippi Valley. Over almost the entire nation, a

relatively dry airmass will be in place, making conditions

unfavorable for thunderstorm development through daybreak on Friday.
