The upper ridge is finally on a slow drift  Southeastward today and Tuesday in a Northwesterly flow aloft.. Expect a dry partly cloudy warm day, with the freezing level possibly topping out at 3500 meters. A weak front will push through Tuesday afternoon with a descending FL (> to 1500 m) and some light precipitation. Warm front followed by a cold front. Wednesday and Thursday are looking cloudy with some periods of moderate rain and the FL fluctuating from 1700-2000 meters.  The ridge rebounds on Friday with unsettled weather and strengthens for Saturday into Sunday with warming temperatures.  Beyond that there is a chance of cooler temperatures next week but likely a similar scenario as the coming week. Hopefully we will see a shift in the pattern by November 23.

Weather Observations for November 5, 2018  taken at 06:00 Hours.

2240 meters        -4, Winds were 35-50 KPH SSE--Horstman Hut
1860 meters        -2, Winds were 10-20 KPH SE   --Rendevous
1650 meters         0, 1.8 mm of precip in 16 hrs     --Pig Alley
  660 meters       +6, Valley Temp, Max Temp Yesterday was +10, 8.2 mm of precip recorded yest

    As of 07:00 Hrs this am we have mostly a cloudy sky with a few breaks and variable visibility.


A weak surface trough will bring some light intermittent showers today in a Northwesterly flow aloft. We can expect unsettled weather into Tuesday with fairly dry conditions. The freezing level will hover in the 1600 meter range today slowly dropping tonight to around 1400 meters. An upper level ridge will push in on Tuesday night and will likely remain in the area until Friday. Low may push into the area Friday! Northerly flow will bring a drop in the freezing level for Wednesday and the FL could go as low as 1000 metes during night time hours. May see a few spikes in the FL with daytime heating but certainly looking colder than it has been for the remainder of the week. Long range models are not consistent beyond Friday but the trend could be for a dry period into early next week. Some cloud has the potential for coming over the top of the ridge for unsettled weather Friday with a slight chance of some very light intermittent precip. Likely nice on Saturday and unsettled Sunday. Time will tell!!
