Boulder, Colorado Weather: 7/10/18

Yesterday was hot and sunny.  The students had no issues with observations last night.

This morning has been sunny, warm and still.

The NWS in Boulder, CO, forecasts a sunny day, with a high temperature of 94 F.  The winds will be from the west northwest at 6 mph, becoming calm in the afternoon.  This evening will be mostly clear, with a low temperature of 64 F.  The winds will be from the east southeast at 6 mph, becoming west after midnight.

The NWS in Boulder, CO, has issued a Hazardous Weather Outlook concerning hot, dry weather again today.

The visible satellite image shows no clouds over the state today.  This image has been excluded from today’s post.

The 12 Z upper air sounding from Boulder shows a drier atmosphere today as compared to yesterday.  There was 0.52 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 1657 m.  There was a small thermal inversion near the surface, and the 0-3 km average lapse rate was 4.9 C/km.

The hodograph shows that there was 2 kts low-level shear (due mostly to directional changes) and 18 kts deep-layer shear (due mostly to speed changes).

The surface observations (from the SPC Mesoscale Analysis Map) show mild temperatures and moderate humidity, based on the dewpoints.   The skies are clear, and the winds are generally southerly, statewide.

The surface pressure chart shows that there is some higher pressure over southern Colorado this morning.  The RAP shows that the pressure will drop with diurnal heating, but no strong pressure gradients are expected over Colorado.

The NAM 250 mb chart shows easterly flow aloft around an elongated upper-level high pressure system.

The HRRR simulated reflectivity shows no precipitation is likely today in the Denver Metro area.  This image has been excluded from today’s post.

The HRRR predicts that the high temperatures for Boulder will peak in the mid 90’s by 23 Z.

The HRRR shows that the winds in the Denver area will remain light.  This image has been excluded from today’s post.

The NAM shows clear skies over Boulder during our observing window.

The HRRR agrees as well.

Today will be a warm, sunny and still.  The participants should be able to make observations tonight without too many difficulties.
