Seasonal Forecasts
We have a highly anomalous upper air pattern covering North America with a textbook Omega block and deep upper level cut off low trapped in between. This is creating an extreme and ongoing flood situation over Texas with epicentre being Houston! Surrounding the upper cut off, temps have been running 10-30F above normal and as a result we’re seeing all-time […]
You know that what happens within one area of our atmosphere, there’s often a ripple effect downstream. As high pressure continues to build in over the UK, so southwest winds have picked up ahead of an Alpine low and that means a surge of summer into Greece, Turkey, Bulgaria, Romania into Ukraine. Check out these highs over […]
The final tally from the Colorado snowstorm appears to be an impressive 50.6 inches near Pincliffe. Now the big story turns to the Texas flood emergency. As is often the case, the models have simply failed to see just how much rain was going to fall within just the first 24 hours never mind 5 day […]
Don’t put the winter clothes away just yet. You’ll thank me by the weekend! The NAO goes briefly positive during this week which means Greenland cool’s (-40s back over the interior this morning) and ridging establishes over Ireland and UK providing fine, dry and settled conditions. Early week gales across the NW of Scotland eases down. Sunshine and […]
The system which had all the signs of being a biggy, was just that. The system as expected dove into the Four Corners where it drew on moisture warm, moist air from a warmer than normal Gulf. As a result, coupled with tremendous orographic lift, 1-4ft of snow fell from Denver up into the high country. While upwards of […]
We’ve seen coverings of snow and snow showers in the air even through the sunny afternoon hours of late. How unusual is this for mid April, a time when the sun is as strong as late August? Sure it may be late in the season and your ready for summer warmth, especially when you can enjoy daylight till […]
The long anticipated, long duration snowstorm has begun for Denver and Front Range. In the latest infrared loop below, note the spin over the Four Corners, acting as a wheel, with nice wrap around moisture stream being drawn in from the Gulf of Mexico. Also note the fair up of convection over the Central Plains where severe […]
Well the strong SSWE (sudden stratospheric warming event) back in March sure is doing it’s dirty work this April with arctic cold and snow the talk of the town across parts of South-Central, Midland and Eastern England, Wales and Scotland today and it’s unlikely over yet. This morning’s 500mb height anomaly. Check out this rather Christmas card scene […]
The 2016 El Nino has dominated the entire global weather circulation, driving the warmest winter on record for some across the Northern Hemisphere. However, it’s vast influence isn’t waning despite the El Nino waning with waters cooling dramatically off South America’s west coast. As expected in a Super El Nino’s weakening phase, a large low pressure system crossing […]
It was a cold start to Friday and this chill deepens later today and particularly this evening as arctic air meets a low coming up from the SW. While sleet and snow showers run the chilly north flow over Scotland and N England, it’s more organised moisture meeting the cold over the N York Moors and […]
