The strengthening upper-level ridge across west-central Europe is underway, the atmospheric pressure has already risen towards 1050 mbar across parts of United Kindom. The mid-1040s are reported across France, Benelux and W Germany, near 1040 mbar over the Alps and Denmark. The highest surface pressure is expected tonight, likely reaching 1050-1051 mbar in some parts […]

The post Jan 19th, evening UPDATE: surface pressure readings across UK Wales and Ireland are reporting 1048-1049 mbar and rising – *above 1050 mbar* expected tonight appeared first on Severe Weather Europe.

Half of winter is already behind us. This is usually the time when we take a first look at spring, to see what the early projections are and what to expect. We are also going to have a look at how the last winter month, February, might look. If you are interested in the theory […]

While a large part of Europe is expecting an extremely high-pressure system with pressure readings 1045-1050 mbar until Thursday, there is a very interesting but dangerous feature developing – a deep upper-level low over the Iberian peninsula. It was re-developed from the North Atlantic wave we have been monitoring on Friday – the cyclone was […]

The post Rex-block pattern results in warm-core cyclone / #medicane in SW Mediterranean and huge amounts of rain/snow across eastern Spain this week – flooding threat expected appeared first on Severe Weather Europe.

This morning, a huge temperature difference occurred over Finland. The extreme north Lapland station Utsjoki Nuorgam reported -36 °C while the capital Helsinki in far south Finland reported +5 °C – that is 41 °C difference! This huge temperature contrast over Finland is the result of advection of very cold air mass from Arctic Russia […]

The significant pattern flip is underway across Europe as an extensive upper-level ridging – Rex block is developing this weekend. Surface pressure reading across UK and Ireland is already reaching the upper 1030s and rising, expected to push very near 1050 mbar by Monday morning. Pressure should rise above 1045 mbar also across central Europe […]

As we discussed yesterday, yet another explosive development of the extra-tropical cyclone was expected today. An upper wave ejected from eastern Canada into the Northwest Atlantic and deepened, resulting in explosive cyclogenesis at the surface. The satellite presentation is simply outstanding and reveals some very interesting details of the Arctic air mass advection behind the […]

Like we didn’t have ridging pattern for several weeks now, there is an exceptional event coming in the next days. A very strong upper-level ridging develops over eastern parts of North Atlantic, expanding into western and central Europe. As a result, an associated surface high-pressure system develops and brings *extremely* high surface pressure. A large […]

The post An *EXTREMELY HIGH* surface pressure develops over Europe through Sunday and Monday – 1048-1050 mbar will be possible in some areas! appeared first on Severe Weather Europe.

Tropical Cyclone #Tino has strengthened into a Category 2 system today, packing maximum sustained winds of 65 knots and central pressure around 970 mbar. Its center was passing very close to Vanua Levu island in Fiji earlier. Satellite imagery indicates a very deep burst of convection is really making this system rather healthy as it […]

The post UPDATE: Tropical Cyclone #Tino upgraded to a Category 2 – explosive storms are brushing the Vanua Levu island and eastern Fiji archipelago with severe winds and dangerous flooding threat appeared first on Severe Weather Europe.

Here is the update on the developing powerful winter storm over the United States today. A Lee cyclone is deepening over the High Plains, drifting northeast with a strong cold front pushed north across the central Plains. Freezing rain is ongoing near the front while snowfall is intensifying to the north of it. Surface analysis […]

We have discussed about the explosive development of the new extra-tropical cyclone in the Northwest Atlantic this morning, but there is more in the North Atlantic today. A relatively small, but intense and very photogenic cyclone is moving east to the immediate north of the Azores. This system is at its peak strength right now […]

A positive NAO pattern continues – meaning above normal activity of the Atlantic storms. An upper wave is currently ejecting southeast Canada and expected to develop yet another rapidly intensifying extra-tropical cyclone today. Models are forecasting a violent windstorm again. Thankfully, the system will stay over the open waters of Northwest Atlantic during its peak […]

The post Another explosive cyclogenesis will take place over the Northwest Atlantic today, will push severe windstorm and major waves towards Greenland and Iceland over the weekend appeared first on Severe Weather Europe.

An Invest #93P has been showing some impressive convective activity since yesterday, spread across a large area to the north of the Fiji archipelago in the South Pacific. Its maximum sustained winds have risen to 40 knots, becoming a Category 1 Tropical Cyclone #Tino – the 3rd of the Australian / Fiji tropical season. The […]

It didn’t last long to get another strong cyclone moving into western or northwestern Europe. After the violent windstorm #Brendan on Monday, Jan 13th, another quite rapidly deepening cyclone has formed just shy west of UK today, moving towards the Faroe Islands and the Shetland Islands. Its central pressure is currently around 975 mbar and […]

On January 12th, 2020, a phreato-magmatic explosion began at Taal volcano, in the Philippines. It was a violent, but short-lived eruption. Now, scientists fear, that something bigger might be coming from Taal. Below is a satellite animation, showing the growth and spreading of the large ash cloud during the first eruption on Sunday. The initial […]

A gradually organizing Invest #93P in the South Pacific is delivering some exceptional satellite imagery, locally pushing cloud tops to around -90 °C! That’s extremely high! #93P is on track with its future behavior, expected to pass very near the Fiji archipelago in the coming days while strengthening. Here are some pretty remarkable satellite images […]
