Early Morning WRF-GFS Forecasts


This post is a continuation of the previous one.
------------------------------------------------------------
The Univ. of Arizona, Atmospheric Sciences Dept., high-resolution WRF-GFS forecasts from the 0600 UTC runs last night are quite interesting. The forecast for late this afternoon indicates isolated showers and thunderstorms developing along the border and then extending northward into Santa Cruz and central Pima county.
------------------------------------------------------------
The top graphic shows the WRF prediction of composite radar at 3 pm Monday afternoon and the bottom graphic shows the same for 3 pm Tuesday afternoon. So, the WRF model predicts scattered showers and some thunderstorms for most of the eastern half of Arizona both tomorrow and Tuesday.
------------------------------------------------------------
So the start of the new week will be considerable more interesting than was the start of last week.
