May 13, 2013

Lots of water in Green Lake, the spit was submerged yesterday morning.

Mountain drainage systems were maxed out.

At 2240 meters the temperature was -1, winds were 15-20 KPH from the E. At 1550 meters the temperature was +3.5, no new snow with a  base of 136 cm. 5.5 mm of rain was recorded in the precipitation gauge. In the valley it was +9. Observations taken at 08:00 Hrs this AM.

For the forecast we can expect a wet day with a cool upper trough moving through the area today associated with a SW flow aloft. The trough is very active and electrical activity is possible today, especially south of our zone.  Tuesday appears to dry out with periods of light precipitation. The remainder of the week looks unsettled with cooler temperatures and seasonable conditions. Guesstimates; Today 10-15 mm, Tuesday 1-3 mm, Wednesday 1-3 mm, Thursday 1-3 mm. Freezing levels will drop to 1600 meters this evening, rise to 2000 meters tomorrow afternoon and then back down to 1600 meters for Tuesday evening. For the remainder of the week the levels will fluctuate from 1800-2400 meters. It was snowing at 2200 meters yesterday evening.
