KPWN - Tuesday, October 30th

High pressure moving in behind upper level trough which is now over open sea. Without much heating on Monday, and calm winds early Tuesday morning, we should see radiational cooling. Could see temperatures dip down below freezing. As the high approaches, pressure gradient should tighten during the early afternoon hours and with northwesterly flow at the surface, provide a little bit of compressional warming off of the White Mountains in New Hampshire. Daily maximum temperature should be much higher than Monday especially with decent daytime heating. Gradient will decrease toward 0Z and winds should quiet down and even shift to southerly winds which should keep Tuesday evening temperatures mild. Stable soundings and no significant moisture negate possibilities for precip.
