Well, the morning satellite picture shows the high pressure area centered west of British Columbia area, keeping us under the chilly northeasterly flow. As there will be little change in the ridge today or tomorrow. We can expect mostly sunny to sunny skies today and tomorrow with easterly winds 4-8, and highs near 50. With the winds tonight and tomorrow night mixing the lower levels and the surface temperatures, we likely do not get as cold as we have the past couple of days, still with mostly clear skies, the lows still down near 32.
Things get a little trickier over the weekend with the models offering several different outcomes. It looks like Saturday we start to see some clouds ahead of a trough dropping down from the northwest, with calm winds the highs near 46. We have a slight chance of light rain late Saturday night with cloudy skies, associated with a weak front that moves across. It appears the colder Arctic air will remain north of the area so the snow level will be between 2000-2500’ with the overnight low down to 37.
Still cloudy with a slight chance of rain Sunday, highs near 46, a little better chance of rain Sunday night, the lows near 36, the snow level 1800-2300’.
By Monday, the models get even more confused with even more options to choose from. About a third of them say high pressure builds back in, more of the same conditions would develop to bring a stronger cold front in with over an inch of rain; a couple other models suggesting snow from this event. There are a few more that push everything elsewhere, leaving us high and dry so to speak. So, what did we come up with?
Monday, cloudy with a chance of rain during the day, a better chance that night, snow level still 2000-2500’, highs near 46, lows near 36. Tuesday some rain is likely, we think, the snow level 1800-2300’, highs near 45, then the snow level falls to near 1500’ that night, lows near 33. Still a chance of rain on Wednesday, the snow level at 1600’ with the high only near 43, the snow level falls to around 1000’ Wednesday night with the lows close to near 32.
We have one more day and few more computer runs before the weekend. Hopefully the picture will become a little clearer. Ahhh, the fun of forecasting.
