Westminster, CO, to Gillette, WY

We had a nice sunset last night:


Today is my last morning in Boulder, CO.  We will venture to North Dakota, starting this afternoon.  I have things to tie up here in Boulder, so I don’t know when I will start driving, so I don’t know where we will end up spending the night.  I have estimated New Castle, WY for now.

This morning has been mild, hazy and still.

The NWS in Boulder, CO, forecasts (for Westminster, CO) a mostly sunny cloudy, with a 40% chance of scattered showers and thunderstorms, and a high temperature of 86 F.  The winds will be from the north at 5-8 mph.

The NWS in Rapid City, SD, forecasts (for Gillette, WY) a partly cloudy night, with a 40% chance of scattered showers and thunderstorms, and a low temperature of 55 F.  Winds will be northeast 6-8 mph, becoming west after midnight

The NWS has issued a Hazardous Weather Outlook concerning strong thunderstorms in the afternoon.  These storms will have large hail and gusty winds.

Visible satellite imagery shows heavy cloud cover over our entire route today.

The water vapor imagery shows plenty of moisture aloft associated with the cloud cover.

The surface observations (from the SPC Mesoscale Analysis Map) show mild temperatures and low humidity (based on the surface dewpoint depressions). The skies are clear and sunny over our route.  Winds are light and variable.

The surface pressure chart shows there are no strong pressure systems or gradients, and none are expected to develop over the next six hours.

The HRRR simulated reflectivity shows storms will fire in the early afternoon and we may see an isolated shower or thunderstorm along our route.

We will see our high temperatures along US-85, depending on when we leave and how far east we go.  According to the HRRR, temperatures will reach the mid-90’s in the afternoon.

It looks like a warm and partly cloudy drive today, with a few afternoon showers and thunderstorms possible.

Thank you for reading my post.
