Yesterday, was a pleasant day in western North Dakota. We drove around the Theodore Roosevelt National Park with the windows down, and did a few short hikes.
This morning has been mild, mostly sunny and still.
The NWS in Bismarck, ND, forecasts (for Dickinson, ND) a mostly sunny day, with a high temperature of 80 F. The winds will be from the northwest at 5-9 mph.
The NWS in Boulder, CO, forecasts (for Westminster, CO) a mostly cloudy night, with a 50% chance of thunderstorms (some of which may be severe), and a low temperature of 57 F. Winds will be from the northeast at 5-8 mph, becoming light and variable after midnight.
The Storm Prediction Center (SPC) has issued a Marginal Risk for part of our travel route. The primary threats will be large hail (2″) and damaging winds (>70 mph). We will have to be on the lookout for these storms as we head southwest.
Visible satellite imagery is unavailable at this time.
The surface observations (from the SPC Mesoscale Analysis Map) show mild temperatures and high 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 that storms are expected to fire just east of our travel path. We may be looking at a bunch of back-sheared anvils at sunset.
We will see our high temperatures in eastern Wyoming, depending on when we leave and how much time we spend at different places. According to the HRRR, temperatures will reach the upper 70’s in the afternoon.
It looks like a pleasant drive this morning and afternoon. We will have to watch the radar closely this evening to avoid running into severe storms as we enter Colorado.
Thank you for reading my post.
