Winter Storm Titan: Ice Storm Possible for Ohio Valley; Snowstorm for West, Midwest, Northeast
  • Saturday: The main event east of the Rockies will begin to unfold as snow spreads east across portions of the Plains and Upper Midwest. For the Northern Rockies, this will just be a continuation of snow from the previous, weaker disturbance. Widespread snow is likely across much of southern Montana and Wyoming, while farther south the snow will be more tied to higher elevations. (See inset map for details.)
  • Sunday: The more significant part of Winter Storm Titan begins with snow, sleet and freezing rain becoming heavier. A stripe of significant ice accumulation is likely Sunday and Sunday night from the Ozarks through much of the Ohio Valley with snow farther north from the central Plains into the mid-Mississippi Valley and Ohio Valley. These threats spread into the Mid-Atlantic and Northeast Sunday night.
  • Monday: Snow/sleet tapers off in the Ohio Valley and Appalachians, but continues along the I-95 Northeast corridor, before tapering off in the afternoon and evening. Ice/sleet areas early in the day in the Mid-Atlantic states should changeover to snow by Monday morning.

Weather Story (click the image for a higher resolution image).
EVEN WORSE CONDITIONS will develop tonight as a second, more impressive surge of arctic air. Travel will be significantly affected and could become very dangerous along all corridors leading down from the Continental Divide due to major blowing & drifting snow along with whiteout conditions. Blowing and drifting in some places may be crippling at times! Locations particularly susceptible to these arctic blasts such as the Northern Flathead Valley, Columbia Falls, Badrock Canyon, Missoula (especially downtown), Hellgate Canyon, East Missoula & Bonner along with all other communities along those above mentioned travel routes including Helmville, Avon, Garrison Jct & Clearwater Jct. Further exacerbating the blizzard effects tonight will be the addition of 6 to 10 inches of fresh snowfall we've seen today. Please monitor the latest weather conditions before venturing through these areas starting tonight and continuing into Saturday morning. And if you must travel, please consider preparing an emergency kit to keep in your vehicle should you become trapped by the weather.

A level 1 was issued for SW France mainly for an isolated tornado and large hail event.

A level 1 was issued for Corsica mainly for excessive rain.

A level 1 was issued for W-CNTRL Italy mainly for an isolated tornado event.

A level 1 was issued for the Balearic Islands mainly for an isolated tornado risk and strong to severe wind gusts.


Most of Europe are covered by a branch of the polar vortex. This configuration causes widespread cool to cold mid-levels. Driven by a 60 m/s mid-layer streak, an impulse dives to the SE and crosses France during the forecast. This feature overspreads the warm SSTs of the W-Mediterranean during the evening and overnight hours. Other than that, weak forcing and/or meager BL moisture result in another quiet day for DMC for most of N/C/E Europe.

Overall BL moisture remains meager at best, excluding the Mediterranean, where moderate air mass modification assists in pockets of seasonable moisture.

A level 2 was issued for western France and the northern Bay of Biscay mainly for severe wind gusts.

A level 1 was issued for north-western France and the Bay of Biscay mainly for severe wind gusts.


A broad region of weak geopotential and rather cold mid-levels is situated across Europe. To the west, an Atlantic ridge is surrounded by two strong mid-level jet streaks that turn to the south-east when entering Europe. They will affect the British Isles, France, and the Bay of Biscay region on Thursday. At lower levels, rather cold and dry air will limit thunderstorm potential over most places. Moisture gradually increases to the west, but rich low-level moisture is not expected. Best moisture is forecast across the Mediterranean Sea that also overlaps with steeper lapse rates.

Twin Cities, MN,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

Graphical depiction of the weather story for today.Confidence is high for difficult or impossible travel conditions across a good portion of southern and western Minnesota Wednesday afternoon and Wednesday night. Wind gusts of 50 mph will bring widespread blowing and drifting snow with some drifts exceeding 3 feet in open areas. A Blizzard Warning is in effect for those areas most likely to experience these conditions, with a Winter Weather Advisory in effect for slightly improved, but still difficult condition

No threat levels have been issued


A deep trough, filled with seasonably cold airmass at mid-levels will progress from the Atlantic towards Western Europe and the Western Mediterranean, amplifying to the Northern Africa. Trough is expected to "narrow" down and start to fill in during the forecast period. Just to the west, a pronounced short-wave will rapidly translate eastwards in the exit region of cyclonically curved delta of the 70 m/s jet-stream at 300 hPa. A deep low pressure system will be associated with this short-wave, exhibiting potent LLJ ahead of the progressing frontal boundary. Towards the eastern Europe, rather insiginificant weather pattern precludes any DMC with dry low-level airmass and weak lapse rates.

There will generally be 3 regions that may experience DMC during the forecast period:

1/ Coastal areas of the British Isles, associated with the post-frontal airmass with the steep lapse rates. Embedded convection along the front itself is not ruled out. Higher values of CAPE will be precluded by insignificant overlap of favourable lapse rates with more abundant moisture. This should limit the severe weather threat.

2/ In the post-frontal airmass especially over Southern / Mid France, under cold mid-level temperatures, with mixing ratios of just around 5 g/kg . Weak shear and low CAPE values (on the order of few hundreds J/kg) should preclude threat of severe weather.

3/ Ahead of the weak frontal boundary over the Western Mediterranean - from Algeria towards NW Italy. Here, better low level moisture might yield slightly higher CAPE values than in the remaining areas, but weak vertical wind shear should not allow for any well organised storms capable of severe weather.

Weak mid-layer height gradients with numerous large-scale vortices linger over S/C and E-Europe. A cyclonic vortex over N-Algeria rotates east and flattens over Sicily/Malta. A NW-SE elongated upper trough over SE-Europe offers no significant motion to the NE. Numerous cyclonic swirls mark the respective centers, which reform constantly on different places within the broad trough. Along with downstream ridging, blocking ridge-over-trough pattern persists over E-Europe.
Most active feature will be a slowly filling 970 hPa depression just north of Ireland. Attendant cold mid-layers overspread a vast area from N-Spain to Scotland during the night.
