Forecast for Next Few Possible Snow Storms to target United States |

Winter Storm Decima has brought 4-8" of snow to the Lakes, mid west and north west recently, with a rain/snow and ice mix further South.



The system is now leaving the Country, however will still pull in residual flurries across inland parts of the North East away from the Coast, bringing isolated accumulations of 1-3" in the next 48 hours or so.

Although temperatures will slowly be on the rise throughout next week, and by the weekend the South will see a significant temperature rise, further North it will (of course), remain cold with a few minor snow systems we have our eyes on.

The first system as such is one which is developing right now, and will affect the far North on Tuesday and Wednesday, bringing 2-4" in general in a swathe from Washington, into Minnesota, Wisconsin and Michigan on Tuesday, and affecting the North East (anywhere North of PA) on Wednesday, snowfall totals will range from 1-3" although could be as high as 4 or 5 inches in isolated areas.

We then see a relaxation in the snow risk up to Christmas night, with Boxing day bringing the potential for another snowfall, affecting Southern parts of the Lakes.

MAJOR Storm could hit the British Isles on Christmas Day

Some parts of the British Isles have seen an upgrade if you are looking for a white Christmas. However this only applies for Northern and Western upland counties. Elsewhere, and for these areas also, eyes turn to the potential for very stormy conditions as the jet stream fires up. The polar vortex is starting to load its cranks and as a result, the risk of very stormy unsettled and rather wet phase is likely around and shortly before / after Christmas.

See the risk of a white one for your area at our map.



What is known in weather terms as a polar maritime flow, is possible between Christmas Eve and Boxing day, bringing a risk of wintry showers to low lying parts of Northern England, North Wales, Northern Ireland and Scotland, with significant falls of more than 5cm to higher ground. There may also be some transient snow to hills further South, however this mainly restricted to the hills above 200 metres of elevation.

White Christmas Chances On The Rise

Some parts of the British Isles have seen an upgrade if you are looking for a white Christmas. Northern cities have seen the biggest increase, with a 25% increase in recent hours. Go to the page for your area by using the interactive map below.

Chances of a White Christmas this year are sadly slightly less than you would expect on a typical Christmas in the South, however are much higher for both North West UK and North East UK.



Winter STORM Forecast to bring Cross-Country Snow Event this week |

17th/18th December 2016 SNOW STORM:

Forecasts have been issued for increasing chances of another Cross-Country Snow Storm, arriving in the north / mid west on Friday and in the north east/ Great Lakes by the weekend. To see more information for your states, access your area on this Interactive Map.

The forecast path of the storm will be very similar to the storm that has just passed,  Storm Caly, therefore if you saw significant snow from Caly you will likely see another 4-8" later this week and into the weekend. Early indications suggest that the snowfall totals will be slightly higher than experienced in Caly, however will still be mainly rain or sleet say 100-200 miles South of the Lakes, however this forecast is subject to adjustments.

However, there may be a spell of heavy wet snow on the back edge of this system on Saturday night / Sunday, affecting some states further South for example Southern Pa, North Kentucky etc, whom yet to see significant snowfall this winter.

Some parts of the lakes yet again look in the firing line for another decent snow storm, with up to 12" across parts of Michigan, Wisconsin, the far North of Illinois, Indiana, around Chicago up to 14" could fall this coming weekend.

Anywhere South of Pa will indefinitely see rain rather than snow. The transition from rain to snow will occur from southern IL/IN/OH and be snow in the north of these states, which is pretty similar to what we saw in storm Caly.

Please stay tuned for more updates.

What has happened to proper snow in the UK?

The UK's warmer than average weather can be partially blamed on the warm sea surface temperatures close to the United States strengthening the jet stream up to levels too high to support cold weather, or indeed significant snowfall across most of the British Isles.

This area of warm waters fires up the jet stream, that fast moving ribbon of air a few miles above the surface and is caused by the great temperature difference found in winter between the astonishingly cold temperatures over the Arctic and the relatively warm equator.

These Oceanic patterns follow relatively reliable and predictable patterns in the Sun, the "Solar Cycle".

The last time heavy snow fell in the UK was in January and March of 2013, some 4 years ago.

The last severe snowfall was in 2010, which is indeed rather near in Climate terms, and was brought on by the solar minimum. We are due another solar minimum around the turn of the decade.

Heavy snow has fallen more recently in the more prone areas of Scotland and Northern England, however this is expected even in a Westerly air flow.

You may be struggling to remember what proper snow feels and looks like if you live in the South.

Signs are, the closer we move towards 2025, the more likely we are to experience heavy snowfall. Either this winter or next winter will be quite harsh says sods law.

 

BRUTAL Cold Forecast (could be record breaking) at the end of next week.

Brutal cold shot for East / North East by the middle and later part of next week thanks to a chunk of the polar vortex "falling" off the pole and affecting the United States.



The North East and East of the US (including the great lakes), is likely to experience unforgivably cold temperatures later next week with a severe cold spell arriving on Wednesday night before the cold starts to relent somewhat during the weekend. The severely cold temperatures will arrive on Thursday morning for most parts and the Great Lakes may see another snow system / potential winter storm next weekend (please stay tuned for further updates).

turning-much-colder

The current snow storm, winter storm Caly will bring further accumulations in the North East (falling as rain on the Coast), but inland further moderate snow and at times squalls of heavier snow dumping an extra 2-4" where you already heavy snow, giving some areas total storm accumulation of 12-14".

The cold will tend to moderate slightly however still remaining cold in areas that have snow on the ground, however from Wednesday night and on into Thursday, much much colder ( in fact Severely cold ) air will arrive bringing widespread sub zero temps and a potential snow storm next weekend.

Winter Storm Caly the Full Forecast – what you can expect from this winter storm

A Winter Storm will bring significant snowfall accumulations across a large swathe of Northern US this weekend and on Monday across the higher North East - generally 1-5" will fall with the exception being NW Pacific Mountains with up to 12" and also up to 12" for the Great Lakes, in fact parts of West Michigan / Lake Erie Coast South of Buffalo could see up to 18" by Tuesday.



Reaching the North West tomorrow, Mid West on Saturday Night and the Lakes by Sunday afternoon, this is our first named storm and significant snowfall for many, the snow will reach as far South East as PA and will not affect cities right on the East Coast, ie Manhattan.

This map highlights the areas at greatest risk of seeing impacts from Storm Caly in terms of snowfall:caly-98

As you can see the rain/snow border is quite far North and although all of the precipitation hitting the West Lakes on Sunday will be snow, a warm sector, a layer of slightly less cold air in the atmosphere will turn the snow on Monday back to rain for the East Lakes, Northern Ohio and PA, however once you hit Buffalo Northwards it will be all snow.

What you can expect if you are in the area of the storm:

Snow (2-8")

High winds (gusting to 30mph at times)

Blowing snow

Low visibility

Snowfall type will be POWDERY on Saturday/Sunday in the North West and Mid West however will be more wet in the East, especially as the wintry mix arrives on Monday.

Winds will become gusty in the system, very low visibility <0.4km is likely at times due to the blowing snow, an added risk. On high ground above 1,000ft, temporary blizzard conditions may occur however we are not expecting blizzard conditions at major city levels.

You may have recently heard about the Winter Storm, now named "Caly", forecast to affect the North West on Saturday, Mid West on Sunday, and Great Lakes / North of the North East (North of PA) on Monday generally dumping 3-5" of snow in it's path.

Projected Snowfall Totals:

Projected snowfall totals range from 1-4" in the West, and grow up toward 10" across areas close to the Great Lakes ie Chicago. The Storm will gradually head Eastwards, as it does so it will pick up more energy from the South, turning some of the snow back to rain on Monday. However, away from the immediate Coast (New York gets a wintry mix), it will fall as mostly snow with at least 1-4" in the moderately affected areas.

The highest snowfall totals are likely to be in parts of West Michigan, NW PA and West NY, but specifically Southern Michigan where 20 inches could be on the ground by Tuesday, due to the added lake effect showers dumping an initial few inches.

Rain/Snow boundary:

The rain / snow boundary is likely to be 200 miles from the East Coast, although the first energy (named Caly), will be mostly fine powdery snow and falling only as Snow where it does fall in Northern Indiana, Illinois, Ohio and PA,  the second area of energy forecast to arrive on Monday will be somewhat more of a wintry mix of sleet, rain and wet snow for these areas, however is likely to remain as (at least wet) snow for the Great Lakes.

This second bout of energy which will join the main energy on Monday will be more of a wintry mix for states further South whom originally saw snow.

This second bout of energy will also start off as snow, however will transition to rain and sleet for most areas during Monday before transitioning back to at least Wet Snow for areas South of Buffalo, however North of Buffalo expect an all snow event, as this transition to and from Snow will not affect you on Monday.

Snow types:

If your snow falls Saturday: powdery / fine.

Sunday: powdery / fine.

Monday: Powdery North of Chicago, South of Chicago wet and mixed with sleet.
