First week of vacation weather: The heat wave is coming, but violent storms are right behind it

The beginning of this year's vacation is expected to be a period of highly dynamic and demanding weather. Poland awaits a real thermal swing and atmospheric phenomena. The first days of summertime vacation, the last week of June, will be marked by a powerful heat wave, during which thermometers will point even 34 degrees Celsius. However, the joy of the summertime aura will not last long. Just behind the heat wave, a cold weather front will come, bringing violent and devastating storms. Forecasts of leading numerical models and analyses Institute of Meteorology and Water Management (IMGW) indicate unequivocally: we must prepare for the weather rollercoaster.

African heat to welcome summer

The last week of June will begin under the dominance of hot and dry tropic air masses, which will flow through a wide stream into our country from confederate Europe and northern Africa. The climax of the heat wave is expected in Sunday and Monday, June 22 and 23. In these days the maximum temperature will easy exceed the threshold in the majority of Poland 30°C.

It will be the hottest in western, confederate and central districts. That's where mercury poles can fly to 30-34°C. As the synoptists point out, specified heat is the consequence of a strong high-pressure strategy in the south of the continent that effectively transports African heat into Europe. Drivers and travelers should take into account that in the full sun and in the concrete city centres the temperature will be even higher.

Additional burden for the body, especially at night, will be called tropical nights. According to the definition, this is simply a phenomenon during which the minimum temperature during the full night does not fall below 20°C. This makes recovery and remainder difficult, and combined with regular heat can pose a serious wellness risk, especially for the elderly, children and people with cardiovascular diseases. IMGW plans to issue weather warnings of the second, and locally possibly even a third, before the heat.

Rapid weather breakdown: Storms are coming with hail and strong wind

The idyllic, sunny aura won't last long. Already in Monday afternoon from the west the cold weather front enters Poland. Its arrival will be like a collision of 2 worlds – a warm, tropical air mass with a cooler, polar sea. specified a sharp thermal contrast is the perfect fuel for the improvement of powerful and dangerous convection phenomena.

Synoptics with a large deal of certainty foretell that the front will bring organized storm systems, including possibly superstorm cells. The top threat will be:

• Heavy rainfall: The estimated amount of precipitation may scope 30 to 40 litres of water per square metreAnd point even more. specified intense rainfall can lead to local flooding and flooding, especially in urban areas where sewage systems may not be sufficient.
• The Violent Wind: In the storm zone, the wind in the hijackers can scope velocity from 80 to even 100 km/h. specified strong gusts are capable of breaking branches, damaging roofs, and even breaking power lines.
• Hail rainfall: The hail with a diameter of respective centimeters is forecast locally. It can origin crucial material losses, destroying agricultural crops, roofs of buildings and car bodywork.

The region of the most violent storms on Monday and at night from Monday to Tuesday will gradually decision from the west into the country, covering almost the full of Poland. Keep track of weather messages and alerts issued by IMGW and local emergency services.

Temporary cooling and prospects for the remainder of the week

Crossing the atmospheric front will bring Tuesday, June 24, clear, but short-lived, cooling. Temperatures will fall to more comfortable values, oscillating within the limits of 19-21°C in the east and northeast, to 23-25°C In the west. The weather will calm down, although it may inactive be windy in many regions.

From Wednesday, June 25It'll start warming again. The atmospheric circulation will change again, beginning the way to warmer air. The end of the week is mostly bright and very warm, although local afternoon thermal storms cannot be ruled out, which, however, should no longer be as violent as those associated with the front. Temperatures in the second half of the week will emergence again, reaching values from 24°C to 28°C, which will make good conditions for continued vacation holidays.

Expert comment: summertime of extremes becomes the norm

The weather pattern observed at the beginning of the vacation – a fast transition from heat wave to devastating storms – is an increasingly common phenomenon in our latitude. Long-term forecasts Institute of Meteorology and Water Management for the full summertime indicate that both July and August are to be months with temperatures above the multiannual standard. At the same time, the sum of precipitation is to be normal, suggesting that precipitation will be violent and local alternatively than continuous and even.

Such a script is consistent with global climate trends. The rising temperature in the planet increases the energy in the atmosphere, which, on the 1 hand, promotes the formation of persistent heat waves, and on the another hand, powers violent storm phenomena. We must be prepared for specified weather “rollercoasters” to become a permanent part of the summertime months. This requires not only adaptation in the planning of holidays, but besides increased attention to safety issues – from heat protection to securing property from storms. erstwhile planning outdoor activities, the absolute basis should be to regularly check weather forecasts and warnings.
