Spring 2014 (March-May) - Northern Hemisphere (northwest, snowfall, warm, recorded)

[Cambium]

Heads up Mid Atlantic. Check out the latest 00z Hi-Res NAM reflectivity showing line of 40+dbz from PA to Virginia Wed 7pm. Even a line of storms cutting through MA. 32° line west and north of there at that time.

SPC has a Slight Risk of Severe storms http://www.spc.noaa.gov/products/outlook/day2otlk.html

If the sun comes out tomorrow it will create warmth and instability and even a chance of Tornadoes too Philly southward.

Typical spring stuff as strong storm moves across... Severe Storms on South & East side of low, with heavy Snow West & North side of Low.

Current Radar, Temps and Surface pressure as the 992 Low is near Cincinnati

Look at the 2 lines of storms south of Low. And the Heavy snow north of it. Already seeing reports of 2-4" of snow in northern Indiana.



What the storm will produce in the East. Watch out for Flash freezes even if your in the area of Rain. Temps are going to crash Wednesday night

Snowfall reports as of 6AM at some CHI area stations

6.2" Joliet
5.2" Chicago-Midway
5.0" Crest Hill

4.0" Naperville


Midway is now over 85 inches for the season. About another 5 inches to go to beat it's all time record of 89.7 inches recorded in the winter of 1978/79 which is the Chicago's official snowiest winter

Interesting from NWS NY. So when temps are warmer above the surface wind gusts aren't much higher than sustaned winds?

WINDS WILL INCREASE OUT OF THE S/SE IN RESPONSE TO THE TIGHTENING
PRESSURE GRADIENT AS THE LOW PRESSURE TO OUR WEST DEEPENS.

DUE TO THE INVERTED THERMAL PROFILE ABOVE THE
SURFACE NOT EXPECTING GUSTS TO BE MUCH HIGHER THAN SUSTAINED WINDS
AT THE SURFACE.

How Fast?

00z Hi-Res NAM 850mb temps & SLP.

Left is 9pm tonight. Right is 2am.

NYC 50F° to teens within 5 hrs at 850mb. That's fast! Look how tight the gradient is.

I don't want thunderstorms. I want snow. We really get the ****ty end of this storm.

[Infamous92]

I want thunderstorms, I'm not expecting any, but I'd like to be surprised.

Hopefully we can salvage another nice day, it's already up to 56F where I am.

Most unusual dry weather has settled over the Malayan peninsula in the past 6 weeks. Singapore had it's driest month on record in February (official records start in 1869) with just 0.2mm recorded and it has still not seen any rain so far this March.
