Temperatures in Greece are expected to rise gradually, beginning on Wednesday, with meteorologists expecting a new heat wave by the weekend.

The National Meteorological Service issued an emergency announcement that temperatures may rise as high as 40 degrees Celsius (104 degrees Fahrenheit).
The new heat wave will start cranking up the temperatures tomorrow in western, central and northern Greece, when the thermometer will hit up to 38 degrees Celsius (100.4 degrees Fahrenheit).
The most difficult day of the heat wave will be Friday, when temperatures will climb as high as 40C in western central Greece, Thessaly and Macedonia.

Temperatures will reach 38-40 degrees Celsius in many areas on Friday. The high winds in the Aegean will weaken throughout the weekend and temperatures will then rise again gradually over the next several days.

Meteorologists predict that the high temperatures will continue and remain in place through August 15. However, some meteorologists say that it is too early to predict the exact weather for the Greek Feast holiday on August 15th.
