Scotland The cold easterly flow is back thanks to low pressure down to the south, high pressure to the north, these winds have felt cold and have fed wintry showers into eastern areas while it’s stayed largely dry and sunny across the west. Through tonight it’s another clear, cold and frosty night with lows of 0 […]
The incredible April storm has already produced winds of up to 150 mph over Mammoth Mountain and through tonight may produce damaging easterly winds through Salt Lake City thanks to the tremendous pressure gradient between a 1036mb high over western Canada and a sub 985mb low over southern Colorado. While winds scream across the Wasatch and adjacent ranges tonight, heavy […]
It’s been a long, cold and snowy winter across much of the US but as temperatures begin to warm, this puts us all in the mood for warmer days, barbeques, the beach and vacation. As we’re getting deeper into spring, the role of rainfall becomes more and more important as distribution of precipitation can very much determine what kind […]
It may feel like winter is never-ending but today, we can look forward to the warmer weather with my UK & Ireland Summer Forecast 2013. It seems like a very long time since we enjoyed a decent summer here in the British Isles and Ireland. Recent summers have been very much dominated by excessive rainfall […]
It’s going to be a messy week of transition as cold doesn’t want to let go. While Atlantic lows track across the southern half of Britain, swinging a shield of precip north, colder air will filter down from the north setting up a battle this week. It will stay chilly in the North while milder air tries to push up […]
The US weather map is about to go wild early and mid week with a textbook spring storm setting up. A very impressure thermal gradient will set over over the Plains as the system matures over Texas, supporting temps 20-40 below normal over the Rockies/western high plains while it may get to nearly 30 above normal over the interior Mid-Atlantic with 80s as far north as Philadelphia, […]
There is lots of uncertainy showing up in the models and the battle is likely to only worsen through the upcoming week as the extreme blocking pattern reverses right at a time when the atmosphere is transitioning. I want to show you the big flip in the models between yesterday and today with next weekend and also want to show you […]
For about two weeks now I have been saying that once we enter April’s second week, the cold pattern should begin to breakdown and that will happen during next week but it’s once the indexes return to neutral and more so, positive, then we must be watching the models to see whether they hint at ridging and finally the arrival to warmer weather.

Although there’s snow falling across the Northern Plains at the moment, the weather map is relatively quiet at the moment across the US but that changes in a big way early next week as a major spring storm develops from an upper disturbance which swings into California from the Gulf of Alaska. All the key […]
Milder air will arrive as early as THIS weekend as winds fall much lighter than of late and with plenty of strong sunshine, temperatures should rise to between 8-11C. Although it’s still a little below average it’s an improvement at least. As for next week, we will gradually emerge from the fridge as high pressure sinks […]
