NO FLOOD THREAT IS FORECAST TODAY.
Strong high pressure ridging continues to reside overhead, leading to another day of hot temperatures statewide. In fact, temperatures will again nudge up a few degrees over yesterday’s readings, with record high temperatures being threatened (and likely exceeded) at a number of locations across eastern Colorado. With the dry air in place, temperatures will warm up quickly and remain hot into the evening hours, so be sure to stay hydrated and find the shade as much as possible if you must be outside today. Red Flag Warnings are in place across much of the state, as well, so be sure to check with your local NWS office for more information.
A weak mid-level disturbance (red line) embedded in the southwesterly flow aloft will pass over the state today, working alongside daytime heating to trigger a few high-based showers/thunderstorms along/east of the Continental Divide. Much like yesterday, with the high temperature-dewpoint spreads in the low-levels indicating very dry air, little (if any) rainfall will reach the surface. Instead, activity will result in mainly strong winds with plenty of virga.
