The new week is almost upon on us and with it a spell of significant and disruptive snow for some in the U.S with as much as 12″ falling.
Heavy snow will fall from around midday today for Denver and much of Colorado before spreading into Kansas, Texas and Oklahoma later on in the day.
The largest falls will spread from Denver down to Pueblo and South East to Amarillo with many areas hit by 3″ minimum and up to 12″ in the worst hit areas, Some of which will experience whiteout conditions.
Many of these areas will then see an exceptionally cold night with temperatures 20-30 degrees below the expected normal for November.
The band of snow will progress North East over the course of Monday and Tuesday bringing further significant accumulations for parts of New York State, Vermont and Maine before affecting Montreal and Quebec City in Canada.
Much of the United States has had a mild time of it lately with temperatures 2-6 degrees above average in particular around the Lakes & the North East.
Those balmy days will soon be forgotten as all that looks set to change with a freezing northerly which will bring a sharp decline in temperatures next week.
The ECMWF model anticipates temperatures to nose dive from around the 6TH of the month as the first major cold incursion takes place. This spell could last well beyond then as the cold air sweeps as far South as Tennessee.
At this range details of snowfall is to far off to predict however should such a significant cold spell take shape many areas will be at risk of large snowfalls with a particular risk of large lake effect falls.
We will bring an update with more details later in the week but for now its one to be aware of.
Were still over two weeks from Haloween, but it’s starting to feel like Christmas in the Rockies as snow is moving through Colorado, western Kansas and parts of northern New Mexico on Sunday.
Winter weather advisories and winter storm warnings span across eight states through early Monday in anticipation of potentially heavy snowfall and blowing snow.
Snow is falling across many parts of the Rockies and Plains on Sunday morning. The snow is the result of a strong cold front that will eventually reach as far south as the Gulf
Generally, 2 to 4 inches of snow can be expected across portions of Colorado, Nebraska, Kansas and New Mexico through Monday. The highest accumulations will be seen at the higher altitudes. The Sangre de Cristo Mountains, the Wet Mountains and the summit of Pikes Peak in Colorado could see up to 16 INCHES of snow. Strong winds will also create whiteout conditions at various times throughout the day!
Storm Callum is bearing down on the UK and the Met Office has issued a yellow warning.
The warning is for a potential risk to life in the worst affected areas as parts of Ireland, Northern Ireland, Wales and Scotland could see gusts over 80MPH. The worst of the winds reserved for the Scottish mountains which will likely see over 100MPH gusts.
High tides are also expected to coincide with strong winds and those susceptible to coastal flooding need to keep up to date with local authority flood warnings.
The full MetOffice warning reads:
A spell of windy weather is expected on Friday associated with Storm Callum.
What to expect
Some delays to road, rail, air and ferry transport are likely
Delays for high-sided vehicles on exposed routes and bridges likely
Some short term loss of power and other services is possible
It’s likely that some coastal routes, sea fronts and coastal communities affected by spray and/or large waves
Gusts of 50 mph are likely with potential for gusts of 60 mph around exposed coasts and hills. High tides are also near their peak, heightening the risk of coastal impacts due to large waves. Strong winds are expected to arrive across Northern Ireland, southwest England and west Wales during Thursday night, spreading to Scotland by Friday morning. Through the day winds are likely to ease across parts of Northern Ireland and southwest Scotland. Elsewhere after a brief lull, winds are expected to strengthen again during the afternoon. In particular for the far northwest of Scotland including the Outer Hebrides. Here gusts are likely to peak at 60-70 mph during the late afternoon and evening before easing overnight
Straight off the back of Storm Ali the Met Office has now officially named the second storm of the season.
Storm Bronagh is set to hit parts of the British Isles with strong winds and heavy rain of upto 100mm as we go through this evening and into Friday.
Check out the full Met Office warning below…
Between 18:00 Thu 20th and 09:00 Fri 21st
Storm Bronagh brings potential for very strong winds on Thursday evening and overnight into Friday morning.
What to expect
Some damage to buildings, such as tiles blown from roofs or through falling trees and branches, could happen. Injuries and danger to life from flying debris are possible
Road, rail, air and ferry services may be affected, with longer journey times and cancellations possible
Some roads and bridges may close
Power cuts may occur, with the potential to affect other services, such as mobile phone coverage
Injuries and danger to life could occur from large waves and beach material being thrown onto sea fronts, coastal roads and properties
The warning area, now associated with Storm Bronagh, has been extended to cover more of northern England. The likelihood of medium impacts has also been increased.
Regions and local authorities affected:
East of England
London & South East England
North East England
North West England
South West England
Yorkshire & Humber
An area of strong winds is likely to develop across parts of Wales and southwest England during Thursday evening before spreading further eastwards across England. The strongest winds are then expected to clear into the North Sea early on Friday. Most likely is that we will see gusts of 45-50 mph in a few spots inland as well as more widely around exposed coasts. However, there is a small chance that stronger winds will develop in some areas with 60-65 mph gusts possible, particularly overnight into Friday across eastern England. The strong winds will accompanied by short-lived outbreaks of very heavy rain in places.
While many are focusing on the dangerous hurricane Florence, there is another interesting and potentially dangerous tropical system in the Atlantic.
The Category 1 hurricane Helene is heading towards Europe early next week.
Helene is currently still in the central Atlantic, but is moving towards the Azores and it is a beast!
Current satelite images show Helene to be a well defined hurricane with strong winds which could reach in excess of 100MPH.
Helene will eventually become a post-tropical storm and accelerate towards western Europe. It is possible the ex-hurricane Helene will be pushed into British isles and Ireland on Monday and bring gale force winds and torrential rainfall with potentially dangerous conditions.
