Forecast Discussion:
Sorry, it is hot. And is going to be hot through Saturday. And dry.
Figure 1 shows the dry air over eastern Colorado Wednesday PM. We have a high pressure center located overhead again for today (Figure 2). And the center of the upper air ridge right over head again (blue line next to the Longmont pink dot in Figure 3). We are just in the doldrums of summer for a bit.
The temperature anomaly this afternoon will be maximal along I-25 with down-slope flow adding to the compressional heating is shown in Figure 4. This looks to be 10-15 degrees above normal. That puts us in the 99°-102° F area. Oh my.
The longer range forecast:
Though some moisture may return, it won't be much and the ridge will hold strong until Saturday passes. Sunday will see our next cool down and better chance of storms as an upper level trough sends a cold front down (Figure 5). Hold on, this is not Phoenix, it does cool down at times.
