Current map with Upper Heights. Typically Warm, Dry & Sunny under a ridge. Except for convective stuff of course. Not sure if those clouds over Georgia/SC are convective. Temps in the 70s there.
Huge Upper Low over Colorado.
Check out the Thunderstorms in Eastern South Dakota while its snowing "during the day" in western Nebraska!
After what looks to be a mild weekend there's the possibility of a major spring storm in Alberta on Monday.

FROM EDMONTON TO CALGARY BRINGING LIGHT SNOW ALONG IT. A COUPLE OF
CM HAS BEEN REPORTED IN A FEW LOCALITIES OVERNIGHT ALONG THIS
TROUGH. THIS FEATURE IS ALSO SUPPORTED BY A VORT MAX ALOFT THAT WILL
CONTINUE TO MOVE NORTHEASTWARDS TOWARDS COLD LAKE THROUGH THE DAY.
POCKETS OF FOG ALONG THE FOOTHILLS AND PARTS OF SOUTHERN ALBERTA ARE
STARTING TO DEVELOP THIS MORNING IN THE WAKE OF THE SNOW WITH THE
EASTERLY UPSLOPE FLOW.
TEMPERATURES SHOULD BEGIN TO MODERATE THROUGH THE DAY FOR MOST OF
ALBERTA WITH SPRING POKING ITS HEAD IN TO SAY HELLO THIS WEEKEND.

SINGLE DIGITS AND LOW TEENS TOWARDS SOUTHERN ALBERTA. HOWEVER, BE
HAPPY SPRING POPS IN ON THE WEEKEND BECAUSE WINTER RETURNS MONDAY.

WESTERN ARCTIC...THE BEAUFORT LOW IS NOW NORTH OF BANKS ISLAND
HEADED TOWARDS RESOLUTE BAY. THIS LOW IS BRINGING UP TO 5 CM OF
SNOW ALONG ITS PATH. AS THIS LOW MOVES CLOSER TO RESOLUTE BAY THE
SOUTHERLY GRADIENT STRENGTHENS TODAY WITH WINDS GETTING AS STRONG AS
60 GUSTING TO 80 KM/H CREATING BLIZZARD CONDITIONS THIS
AFTERNOON THAT WILL LAST UNTIL THIS EVENING.
The bees have woken up! and bugs. But nothing to pollinate yet. And Do they know they wont see this pattern until May probably? No more 70s until May. Maybe no more 60s!?
2:30pm. NYC has hit 80°. 1st time since October 10th
Best part about today is this.... WHY CANT SUMMER BE LIKE THIS!??

.A significant winter storm will develop this afternoon and
continue through Saturday night. All precipitation types, strong
winds, and blizzard conditions will occur in this winter storm. A
Blizzard Warning is in effect tonight through Saturday evening
for west central and south central Minnesota. A Winter Storm
Warning is in effect for most of east central and a portion of

Cloud, the Twin Cities, Mankato and Albert Lea are included in the
warning. As well as Rice Lake, Ladysmith and Eau Claire Wisconsin.
A Winter Storm Watch remains in effect for areas north of the

Showers and thunderstorms are expected to continue this morning,
and persist for much of the day as temperatures remain in the mid
30s in central Minnesota to the lower 40s along the
Minnesota/Iowa border. Colder air will begin to move into central
Minnesota this afternoon and evening, changing the precipitation
to snow. In addition to the heavy snow, strong gusty winds of 40
to 50 mph will bring blizzard conditions to west central
Minnesota. The best chance for whiteouts will be late Friday night
across west central Minnesota. The rain will turn to a wintry mix
of freezing rain, sleet, and snow across south central and east
central Minnesota, and west central Wisconsin Friday evening,
before changing to all snow by Saturday morning.
Total snow accumulations of 8 to 15 inches are expected from west
central and southwest Minnesota to east central Minnesota and
northern Wisconsin, with totals nearing 18 inches possible across
southwest Minnesota. Totals will taper off to 4 to 8 inches
across south central Minnesota. There may be a sharp gradient in
the watch area north of Alexandria and Little Falls. In addition,
total ice accumulations of one to two tenths of an inch are
possible across the southern third of Minnesota into west central

A Blizzard Warning means severe winter weather conditions are
expected or occurring. Falling and blowing snow with strong winds
and poor visibilities are likely. This will lead to whiteout
conditions, making travel extremely dangerous. Do not travel. If
you must travel, have a winter survival kit with you. If you get
stranded, stay with your vehicle. The latest road conditions for
Minnesota can be found at 511mn.org and for Wisconsin at
