Boulder, CO, to Newcastle, 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 a mostly sunny day, with a 10% chance of isolated showers and thunderstorms, and a high temperature of 90 F.  The winds will be calm.

The NWS in Rapid City, SD, forecasts (for Dallas) a smoky and partly cloudy night, with a  low temperature of 64 F.  Winds will be northwest 5-7 mph, becoming east after midnight

Visible satellite imagery shows no clouds along our route.  This image has been excluded from today’s post.

The water vapor imagery shows that we will ride in dry air all day.

The surface observations (from the SPC Mesoscale Analysis Map) show cool 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 that there is a low pressure system over Montana that will intensify with diurnal heating.  Even so, no strong pressure gradients are expected to develop over the next six hours.

The HRRR simulated reflectivity shows storms will fire in the late 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 sunny drive today, with a few afternoon showers and thunderstorms possible.

Thank you for reading my post.
