I meant to do a post yesterday about what a great day it was, but day got away from me. So, view above is from 10:00 am MST yesterday morning (Tuesday, February 3rd). View below at 5:00 pm shows some high, thin cirrus to the north and northwest.
This morning I took a quick look at the forecasts from the Atmo WRF-GFS run initialized at 00 UTC last evening - the evening forecast runs include an expanded domain on the 1.8 km grid that includes much of New Mexico.
First, the above graphic shows the forecast of Global Horizontal Irradiance (GHI in W/m2) valid at 1:00 pm MST this afternoon. Model forecasts another very bright and sunny day. From Vaisala here is definition of GHI:
The radiation reaching the earth's surface can be represented in a number of different ways. Global Horizontal Irradiance (GHI) is the total amount of shortwave radiation received from above by a surface horizontal to the ground. This value is of particular interest to photovoltaic installations and includes both Direct Normal Irradiance (DNI) and Diffuse Horizontal Irradiance (DIF).
There is a strong cold front pushing down the High Plains and Front Range this morning, and I was curious as to how the WRF would handle this front. By 10:00 pm tonight (10-m winds above) the front has intruded deep into Texas with strong and cold east-northeasterly winds gusting across the Big Bend Country. The east winds weaken during the night but the model does forecast a period of easterly winds across southeast Arizona late tomorrow morning (forecast below of 10-m winds valid at 11 am). And that's about it for short-term weather - enjoy!
