We have a new tropical depression (four) just declared by the NHC. A feature which models have been all over for the past 4 to 6 days. This is a complex system with a complex outlook. A system which could take a route westward into the Gulf of Mexico, north and stay off the US East […]
We’re catching a break from the wet weather in the Friday through Sunday time frame as ridging between two lows builds into the UK. However, as skies clear tonight, so we can expect the coldest night since spring with a rural frost possible. Come late Sunday into Monday that high shifts into the North Sea and eventually near continent […]
The current 7-day stretch across the Eastern two thirds of the country may well be the hottest of the entire summer from Dallas to Charlotte up to Chicago. For cities such as Indianapolis and Pittsburgh whom have not yet hit 90, we will watch this current heat surge carefully! ECMWF 7-day mean 500mb heights 7-day mean 2M temps/anomalies Yesterday’s highs. […]
After a wet, breezy and cool day, especially wet across northern parts of the UK, the showers thankfully ease as we head into the weekend. Low pressure gives way to high pressure. It’s been a very persistent negative NAO pattern this week with a high west, northwest of the UK while a large low complex spins over Scandinavia. Chilly […]
While the hottest air of summer builds over the South and eventually north up into the Midwest, the Western monsoon has really meant business over the past 36 hours with major flooding causing havoc across the West and Greater Phoenix area in particular. Impressive 24-hour rain totals [s2If current_user_can(access_s2member_level1)] Here’s the write-up from the NWS of Phoenix. […]
I am growing particularly interested in the behaviour and trend we’re seeing with the NAO. Although still a long way off, the type of upcoming winter may already be shown and following the disappointment and bust of last year, I am wanting to look closely and show you what I’m seeing. For EUROPE that is since the US […]
If only it were winter, THIS pattern would be perfect for cold and snow lovers. [s2If current_user_can(access_s2member_level1)] Nice strong blocking high over southern Greenland which the core of this pretty deep trough is centred over the North Sea! The blocky nature of the current pattern means a slow eastward progression with N Atlantic ridging building in mid […]
As pointed out in recent days, we’ve got the chilliest air flow driving south over the UK in several months and it sure is a shock to the system following a mild May, June and July. While chilly with frost and even hill snow across parts of the North as well as Iceland, Scandinavia and the […]
Finally it would appear the African wave train is becoming more pronounced as the Azores high (eastern part of the mid-Atlantic) is weakening and easterly trades are weaken, thus more upward motion! Notice the plume of Saharan dust is further north and west where ridging and large-scale sinking is more prevalent. There’s a lot more […]
The latest CFSv2 weeklies (through Sep 12) shows Greenland ridge/western Europe trough dominance through mid Sep. [s2If current_user_can(access_s2member_level1)] This NORTH ATLANTIC blocking trend is something WE DIDN’T see at this time last year. However, for all you snow geese out there like myself, let’s not get over excited but merely watching this pattern as we head into autumn […]
