Golden, Colorado Weather: 4/6/19

Yesterday, the weather was relatively nice.  There were a few drops of rain in the evening, but not even enough to wet the ground.

This morning has been mostly sunny, mild and still.

The NWS in Boulder, CO, forecasts (for Golden, CO) a mostly cloudy day, with a 20% chance of isolated showers and thunderstorms, and a high temperature of 65 F.  The winds will be light and variable becoming west northwest at 8-13 mph, gusting to 20 mph, in the afternoon.  This evening will be mostly cloudy, with a 20% chance of isolated showers and thunderstorms, and a low temperature of 38 F.  The winds will be from the west northwest at 9-11 mph, gusting to 17 mph.

The visible satellite image shows the mostly sunny skies over Colorado today.

The 12 Z upper air sounding from Boulder, CO, shows a dry boundary layer today.  There was 0.39 inches of precipitable water present in the column.  There was no Convective Available Potential Energy (CAPE) and no Convective Inhibition (CINH).  The Lifted Condensation Level (LCL) was 619 m.  There was a moderate inversion near the surface, and the 0-3 km average lapse rate was 6.0 C/km.  The hodograph shows that there was 8 kts low-level shear (due mostly to directional changes) and 8 kts deep-layer shear (due mostly to directional changes).

The surface observations (from the SPC Mesoscale Analysis Map) show mild temperatures and a low surface humidity.   The skies are clear (according to the sensors), and the winds are light and variable.

The surface pressure chart shows no strong pressure systems or gradients over the state today.  The RAP shows that none are expected to develop over the next six hours.

The NAM 250 mb chart shows light, southwesterly flow over the state today.

The HRRR simulated reflectivity shows that isolated showers are possible by this evening.

The HRRR predicts that the high temperatures for Golden will peak in the mid-60s F by 21 Z.

The HRRR dewpoints will drop into the 20s by this afternoon.

The HRRR shows strong wind gusts are possible in the area.

The HRRR shows that skies will be at least partly cloudy all day today.

It should be a pleasant day in terms of temperature and wind, if we can avoid the rain and the few wind gusts.
