winter hangs on... (pm.25.feb.19)>

Monday's stats:

Low temp: 41.9ºF (5.5ºC)
High temp: 48.9ºF (9.4ºC)
Precipitation: none

It's been a cold late February day, as temperatures continue their slide which has been going on for a couple of days now.  Again we had a lot of back-and-forth between clouds and glimpses of sunshine, but precipitation was restricted to a few passing rain and snow showers in the higher elevations well above town.

If you've been following along recently, you know we're watching a big sprawling area of cold low pressure in the upper-levels of the atmosphere as it gradually oozes and seeps south-southeastward from central Asia into the western and central Himalayan region.  At the same time, there is an increasing draw of moisture coming in from the Arabian Sea to our southwest... however, computer model data runs during the last 36 hours or so have been less aggressive with the amount of moisture available.  As of now, it looks like we could see around a half inch (1.2cm) of precipitation in our general area between later tonight and Wednesday night -- with most of that expected between late tomorrow (Tue) and Wednesday evening.  Temperature profiles indicate that much of that precip could be in the form of snow, even down to our elevation here in McLeod, which could deliver a rare late Feb snowfall event.  Accumulating snowfall this late in the season is something that was not so strange in the olden days, but has become unusual in the past couple of decades.

Thursday and Friday are looking generally quiet, and milder, but then the next in a long long long series of storm systems will begin to affect us by late Saturday into Monday with more wet weather...
