YESTERDAY:
Friday December 27, 2019. 12:00 Hrs. -6.1 Deg C with a 15-30 SW KPH wind.
Overcast Friday morning.
Multiple cloud layers.
A few breaks in the afternoon.
Sunset was at 16:15 Hrs.
Friday afternoon.
Big picture Friday.
2240 meters -3, Winds were 35-50 KPH NE--Horstman Hut
FORECAST:
Yet another weak front pushes on shore this morning in a Westerly flow aloft. We can expect periods of light precipitation this am diminishing by this evening. The freezing level might max out at 1000 meters. For Sunday, a weak upper trough and ridging will bring overcast skies with a dry air mass, might see some breaks and a likely inversion. Unsettled for Monday with weak ridging and some cloud from the low to our North. Might be a dry overcast day! A series of moist frontal bands in a Westerly zonal flow has good potential for some snow next week. At this time Thursday is looking promising for more than our recent 5-10 cm storms. Guesstimates: 3-6 cm by Sunday morning, Trace-1 cm by Monday morning, 1-3 cm by Tuesday morning.
GOES IR image for this am.
Weak short lived cold front for today with warmer temperatures.
Fronts along the coast.
Weak upper trough with mostly overcast skies and some ridging for Sunday.
High looks to be the stronger force for Monday. Deflecting the low. Unsettled weather.
