Will update amounts as soon as the patrol has the data.
As of 07:00 hrs this am we have broken cloud and variable visibility.
For the forecast:
The weakening low will send an upper level trough for this morning, it will be somewhat stable this morning (unsettled) with another warm frontal band expected tonight in a Southerly Flow. The front approaching tonight has the potential to just be South of our zone, only time will tell. A bit warmer than forecasted, with the FL fluctuating from 800 m to 1200 m in the next few days. Moderate snow is forecasted for Saturday with a short lived break in the evening. Sunday morning may also be unsettled before another impulse of precipitation pushes through in the afternoon/evening with periods of moderate snow fall. A very weak ridge may build for Monday with unsettled conditions for most of the day. Guesstimates: 10-15 cm by Saturday morning, 20-30 cm by Sunday morning, 10-15 cm by Monday morning. These amounts will likely be adusted tomorrow.
Light flurries this morning with another impulse tonight.
Unstable this evening.
Some breaks for Monday.
