A major late April cold blast dove all the way to the Gulf Coast this weekend with 30s even reaching Florida this morning. While the South shivered, another wave of unseasonable cold is dropping out of Canada tonight and on the leading edge of this strong cold front, heavy snow shall break out from Montana through Wyoming, Colorado […]
Following a major late winter storm which dumped 17.2 inches of snow in Duluth and as much as 22 inches in other parts of Northern Minnesota, Saturday dawned record cold beneath clear skies, light winds, fresh snow cover and arctic air in place.Temperatures Saturday morning plummeted to -14F at Embarrass in the Minnesota Arrowhead region (NE corner) […]
The forecast challenge has begun as I have figures I am going to throw at next week. They are, London pushes 23C on Wednesday but as the warmth spreads across southern Britain, the cold regroups across north of the UK and will dive south late week. It’s pretty much a case of going from a positive to negative NAO within […]
A few Friday evening thoughts. We could have quite the temperature swing coming up over the next 7 days as the NAO signal flips from positive to negative and that means a sudden shift from warm to late season cold with hill snow. As expected both of today’s runs of the ECMWF show what I’ve said yesterday and throughout this […]
While the core of US drought remains over the Plains, 2013 is changing the shape with the West becoming more arid with time from San Francisco down to LA across to Phoenix and up to Salt Lake City. However, it’s been somewhat wetter over the Rockies thanks to recent late season snowstorms. Even in the Plains, despite severe drought holding […]
Next week remains a forecasting headache and there’s nothing clear cut. Again I use the teleconnection between North America and W Europe and how, even with this upcoming period, the warmth currently over the eastern United States needs to be watched as it gets forced out into the Atlantic thanks to a storm crossing the country. It’s as this warm air gets […]
Scotland It’s been another blustery day with hefty showers to go with it but the good news is that winds ease, clouds and showers dissipate and that means a colder night for all. Don’t be surprised if you have to scrape your car before heading off to work in the morning. Lows of 2C along the […]
In yesterday’s and even other recent posts i’ve been showing you the greater liklihood of seeing troughs back into the East and hanging there, starting this weekend as the storm that’s sliding across the country pulls the trough in. If you live anywhere from Washington DC up to New Brunswick, make the most of the current warmth, […]
For the past few weeks I’ve been saying about there being an increased chance of seeing a secondary warm spell before we cool down considerably towards months end as the NAO/AO flip back negative. There’s a deffinate battle setting up next week between warm and cool over the UK and Ireland and both the ECMWF and GFS are both agreeing and persistent […]
Scotland It’s a real soaker out there this afternoon with fairly strong southwest winds. Temperatures are mild thanks to the warm source region in which winds are blowing from with highs of 12 to 15C, locally 16C along the brighter and sheltered Moray Firth. Through tonight, rain continues to fall heavy for many, especially over the upslope areas of […]
