May 10, 2013

Ground Hog Day again, all week the same weather pattern.

The one thing that is different is the amount of snow melting and evaporating each day.

Even the runs in 7 Th Heaven are melting quickly!!

At 2240 meters the temperature was +9.5, winds were 0-5 KPH from the SSW. At 1550 meters the temperature was +10, no new snow and a base of 154 cm. In the valley it was +5. Observations taken at 07:00 Hrs this AM. Max temps for yesterday were +26.8 in the valley, +18 at 1550 meters and +16 at 2240 meters.

For the forecast the upper level ridge will continue to hold today, before the approaching frontal system moves into our zone on Saturday. Cirrus cloud developing to the West.  High and mid level cloud can be expected for Saturday and rain will start later in the day. The frontal system will continue to bring rain Sunday easing off Sunday evening before an approaching upper trough arrives for Monday. Monday will also bring a day of mostly cloudy weather and showers. Unsettled for Tuesday into Wednesday with a mix of sun, cloud and snow flurries in the upper elevations. Freezing levels for the rain event will start at 3400 meters Saturday evening, Drop to about 2200 meters for Sunday, Drop to 1850 meters for Monday, and go as low as 1550 meters for Tuesday. Guesstimates for precip are 20-30 mm by Sunday afternoon, 10-20 mm by Monday afternoon, 10-15 mm by Tuesday afternoon. These might be a bit high, the frontal system approaching does have the potential for these amounts.

A raven was happily cruising around yesterday.
