Weather It Is (Winter Weather Advisory (3))

Good Late Morning:

This early morning there was some mixed rain and snow in Efrat, but the snow seemed to melt as it passed my kneecaps.  As is typical in winter here, it is often just a tad warm for snow.  Still, we've had close to 100 mm of rain so far this week, which is a blessing.  Snow was reported on the Golan, where it accumulated at least several centimeters.

The coldest temperatures at 500 mb will occur within the next few hours as the axis of the trough moves through.

The passage of the upper trough should bring one last burst of precipitation.

Afterwards, temperatures in the middle and lower atmosphere will fall a couple of degrees.
While this might bring a bit of snow, it looks like the atmosphere will be drying out after the next burst of precipitation.  If there are any snow showers with the passage of the coldest air at 700 mb, it will be a surprise.

Our highest resolution forecast (1.0 km) shows a light accumulation of snow in the area of Hebron, and a very light snow accumulation in the area of Efrat and the western approaches to Jerusalem.

More importantly, some standing water may freeze on road surfaces this evening and night.  Moreover, tomorrow morning should have temperatures in the higher elevations near freezing, so slippery conditions may persist after dawn.

The weather in the next two weeks looks uneventful, so this may be our last chance to see any snowflakes this winter.
