Dangerous Heat Wave From Poland to Ukraine and Romania This Week

An unrelenting heat wave will continue to have a firm grip on eastern Europe for much the new week. Across Germany, the heat will come in pulses as shots of cooler air bring only temporary relief.

While the jet stream and resultant storm track remain draped over the United Kingdom and western Europe, a ridge of high pressure will stay firmly entrenched over Poland, Ukraine and surrounding areas through at least midweek.

Temperatures will soar daily into the lower and middle 30s C (near 90 to middle 90s F) in Warsaw, Minsk, Kiev and Vienna. Highs around 23 C (75 F) are more common this time of year.

Amid this current heat wave, Warsaw set a new all-time August high temperature record on Saturday when the temperature peaked at 36.6 C (97.9 F). The previous record was 36.4 C (97.5 F) from August 1994, according to AccuWeather Meteorologist Tyler Roys.

The temperature peaked at 32 C (90 F) on Monday, marking the seventh straight day of temperatures reaching that threshold. Temperatures will continue to soar the rest of the week with no relief expected through this weekend.

While most summers feature at least a few days of 32 C (90 F) heat in Warsaw, this summer has been extreme with 10 days achieving such a feat through Aug. 10. Since 1994, the only other occurrences of at least seven consecutive days of such heat were July into August of 1994 and July of 2006.

Little relief will come at night with temperatures remaining above normal, resulting in an elevated threat for heat-related illness as homes without air conditioning will remain warm both day and night.

The cumulative effect of the persistent heat will prove extra dangerous for residents and animals who do not find ways to keep cool. Residents are reminded to drink plenty of water, wear light clothing and never leave kids or pets unattended in a sealed car.

Strenuous activities should be avoided during the midday and afternoon hours, the hottest times of the day. If that is not possible, be sure to take frequent breaks.

Following a brief cooldown on Sunday, another surge of unseasonable heat arrived in Berlin on Monday as the temperature again climbed above 32 C (90 F).

Temperatures will continue to climb on Tuesday with a high near 35 C (95 F) before a weak frontal boundary reaches the area on Wednesday resulting in a high of 30-31 C (86-88 F).

The heat will not release its grip on Berlin as temperatures climb back above 32 C (90 F) from Thursday into Friday.

A more potent cold front will finally push across Germany this weekend bringing much cooler air along with the threat for strong thunderstorms.

This front will again struggle to push further east into Poland and eastern Europe; however, at least some modest relief from the heat is possible early next week along with daily showers and thunderstorms.

Meanwhile, the core of the heat is likely to be entrenched across the Balkans from later this week into next week.
