mild for december... (pm.03.dec.12)>

Monday's stats:

Early morning low temp: 50.2F (10.1C)
Afternoon high temp: 60.6F (15.9C)
Rainfall: none

Skies are totally clear at sunset, after a day which featured about 99.5% sunshine -- there were just a few wisps of high clouds in the east early this morning, but they quickly disappeared.  Today's temperatures (both high and low) were the warmest since the 22nd of November at my location in the upper part of town.

We have a ridge of high pressure from the surface into the middle and upper levels of the atmosphere to thank for this fantastic early December weather.  High pressure is characterized by sinking air, which means that the air mass is very stable.  At the same time, temperatures have warmed considerably in all but the lowest levels which creates an inversion -- that's why there was some patchy fog down in the valleys early this morning, with pockets of left-over cold air lingering there, as warmer air moves in aloft.  This is the kind of situation where/when overnight low temps can actually be a bit cooler down in the valley than up here on the mountain slopes.

This mild weather will continue for most of the remainder of the week, but there will be a couple of weak upper-level disturbances passing through to keep things from being totally perfect.  The first will arrive by Wednesday afternoon, bringing an increase in clouds.  The next one will move through Friday night and Saturday, and may give us a slightly better chance of a random rain shower.  Otherwise, nothing particularly unpleasant or nasty is in the forecast at the moment...

MONDAY NIGHT:
clear skies.  mild for this time of year!
low: 11C (51F)

TUESDAY:
mostly sunny and unseasonably mild.
high: 16C (61F)

TUESDAY NIGHT:
a few high clouds possible, otherwise fair skies. 
low: 11C (52F)

WEDNESDAY:
sun, but clouds on the increase.  above normal temps.
high: 17C (62F)

THURSDAY:
sunny to partly cloudy.
morning low: 10C (50F)
daytime high: 16C (60F)

FRIDAY:
both sun and occasional clouds.  temps still wamer than normal.
morning low: 11C (51F)
daytime high: 16C (61F)

SATURDAY:
partly cloudy to mostly cloudy at times.  a bit cooler, with a chance of a light rain shower.
morning low: 11C (51F)
daytime high: 15C (59F)

temps rising... (am.03.dec.12)>

There are only a couple of streaks of high clouds to the east at sunrise this Monday morning.  I've recorded a mild overnight low temp of 50.2F (10.1C) -- that's a full 11F (5C) warmer than the low on Friday morning after our rain/snow episode!

High pressure is building in quickly now, and should dominate our weather scenario through tomorrow at least.  Milder air has been arriving quite quickly and aggressively as well, so I am updating the short-term forecast to reflect that.

MONDAY:
sunshine... with perhaps a few PM clouds.  unseasonably mild!
high: 16C (60F)

MONDAY NIGHT:
mostly clear skies.
low: 11C (51F)

TUESDAY:
mostly sunny.  pleasant temps for early december.
high: 16C (61F)

sun-cloud duel... (pm.02.dec.12)>

Sunday's stats:

Early morning low temp: 47.7F (8.7C)
Afternoon high temp: 58.5F (14.7C)
Rainfall: none

We've just had a stunning sunset, thanks to the assistance of the patches of mainly high clouds across the area this evening.  Those clouds were much more prevalent today than I was expecting, but we still had enough sunshine during the morning into the mid-day hours to bump our high temp up to the highest in 10 days.  If we'd had full sun today, I'm sure we would have surpassed 60F.  This current air mass is considerably milder than what we were experiencing late last week.

The high clouds today were manufactured by a weak upper-level disturbance which is located just to our west-northwest, but is fizzling out.  A ridge of high pressure should build in from Monday into early Wednesday, keeping our temps near or a bit above normal for early December, while providing us with a  majority of sunshine.

There will be another weak disturbance late Wednesday, and then a slightly stronger disturbance moving in on Friday.  Right now, I'm not seeing any kind of intrusion of moisture to accompany these disturbances, so rain chances will be scanty at best right through the week.  Just be aware that the sunshine will be challenged by periods of clouds from time to time.

SUNDAY NIGHT:
partly cloudy.  seasonably cool.
low: 8C (47F)

MONDAY:
sunshine and a few clouds.
high: 14C (58F)

MONDAY NIGHT:
clear to partly cloudy.
low: 9C (48F)

TUESDAY:
mostly sunny and mild for december.
high: 15C (59F)

WEDNESDAY:
a mix of sun and some clouds.  unseasonably mild.
morning low: 9C (49F)
daytime high: 16C (60F)

THURSDAY:
sunny to partly cloudy.
morning low: 9C (48F)
daytime high: 15C (59F)

FRIDAY:
partly cloudy and mild.  an isolated PM sprinkle or light shower?
morning low: 9C (49F)
daytime high: 16C (60F)

rapid rebound... (pm.01.dec.12)>

Saturday's stats:

Early morning low temp: 44.2F (6.8C)
Afternoon high temp: 56.3F (13.5C)
Rainfall: none

Although temperatures were just a shade below normal, today was about as perfect of a start to the month of December as we could ever hope for.  There were a few cumulus clouds struggling to develop over the mountains after about 1:00pm and a few high cirrus clouds in the southwestern sky at sunset, otherwise the sunshine was the dominant force of the day.

The remaining couple of inches of slushy snow has melted from Triund and other high grassy slopes, leaving the remaining snow cover from our recent storm on the rocky Dhauladhars proper.  Thanks to the sun, and some steady warming in the mid-levels of the atmosphere, we've experienced a rapid rebound from the biting wintry chill of just a day or two ago.

There are some very minor disturbances expected to drift through during the coming few days, but our air mass should remain pretty much bone-dry, with nothing more than occasional patches of high clouds or perhaps an afternoon build-up of mountain cloudiness anticipated.  This weather pattern favors a return to milder temperatures as well, so all in all, it looks like we're in for some relatively pleasant December conditions as the new week unfolds...

a few high clouds possible... otherwise mostly clear.
