FORECAST:

The upper level ridge will begin to shift East today allowing clouds to move in to the area in a Southwesterly flow. The first of a series of fronts will arrive tonight with wet warm windy conditions into Wednesday. The Fl should drop to about 1600 meters this evening with the arrival of the strong moist SW flow. Still some guessing in the FL for Wednesday but hopefully the day starts with the FL around 1600 meters slowly rising throughout the day to a high of 2200 meters, dropping again to 1600 meters by Thursday morning.  A cooler front will arrive for Thursday with light/moderate precipitation, with the FL dropping to just above surface by the evening. A broad upper trough will move in for Friday into Monday with unsettled weather, cloudy at times but with some breaks and a fluctuating FL. Values will be as high as 1000m and as low as surface. Guesstimates: 15-20 cm above 1500 meters by Wednesday morning, 30-50 mm of rain by Thursday morning, 15-20 cm by Friday morning, 4-6 cm by Saturday morning.



    Clouds will develop ahead of the frontal band.

   High pressure will slide East today with the first front arriving tonight.

    Front is heading our way!!


   A bit of a Pineapple Express on its way, Wednesday.

    Low will be over us Thursday, with cooler temperatures.

   Happy Valentines day.
