looming reality check... (pm.07.dec.12)>

Friday's stats:

Early morning low temp: 54.1F (12.3C)
Afternoon high temp: 62.6F (17.0C)
Rainfall: none

We're still dealing with a few high clouds just after sunset on this Friday evening.  The high overcast was rather thick at times today, but we also had some glimpses of sun here and there which allowed this mild air mass to surpass 60F for the fifth straight day.  This has been quite a streak of above normal temperatures we've been enjoying this week.

The latest upper-level disturbance moving overhead today was responsible for the high cloudiness -- but with humidity remaining right around 35%, it's been virtually impossible to squeeze out a shower.  It looks like there could have been a few drops of rain, sleet or snow up on the highest peaks this afternoon, but that's about it.  We have what seems to be a nearly endless train of disturbances scheduled to move through during the coming week or so, with the potential for us to come up with at least some light rainfall amounts before Wednesday rolls around.  Significant precipitation doesn't look promising, but keep a close eye on the forecast as we watch the latest developments.

One thing appears certain -- we're going to lose these mild temperatures quite soon.  There will be a modest cool-down over the weekend, but extended range computer model guidance is pointing to a dramatic return to below normal temps by the middle of next week.  The harsh reality of the season may be a bit shocking by Tuesday and Wednesday.
