A weak reinforcing cold front moves through late afternoon into evening Tuesday. A weak disturbance along this front will bring light precipitation in the form of snow. QPF values have been consistently low, with amounts ranging from 0.06 to 0.11 inches water. No low pressure development is expected with this disturbance.
This translates into a light snow, a coating to 1 inch total by about midnight. This snowfall potential has looked consistently unimpressive. I’ll keep an eye on it.
Monday 8 AM Update: Last night’s NAM and GFS have increased the QPF to about 0.21 inches water, or 2-3 inches of snow starting after 6 PM Tuesday evening. The QPF amounts are surprisingly similar.
Keep in mind that the late night model runs are often inconsistent and unreliable. Will keep an eye on this!
