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 […]
While it may be warm now from the Mississippi Valley on east, don’t get use to it. With the PNA going positive and both NAO/AO going negative, this pattern takes the mean trough east while riding builds over the West. By this weekend, it will be much cooler in the East. Remember the QPF I showed you […]
The slow movement of the second low tracking from Nevada into the Plains states will mean snows continue falling over the Colorado and Wyoming Rockies tonight and throughout tomorrow, adding to already large totals for some areas. As the system dips SE of Denver tonight, expect upslope snowfall to increase over the Laramie Range as well as down […]
Scotland A blustery night to come, as winds ease and with clear skies, it turns cooler. However winds will pick up through the second half of the night as the next front pushes in from the southwest, bringing another spell of wet and windy weather tomorrow with southerly gales. Everywhere will see a spell of heavy, […]
The secondary low that has been closely monitored in recent days is now producing snowfall over the Rockies and now it’s looking like the focus of heaviest snowfall will be north of Denver due to the low tracking a little too close to Denver. This was highlighted back in yesterday’s post. In saying that, Denver may […]
