A solid high-pressure system brought clear skies to the area last week and will keep Friday, Saturday and Sunday in the same pattern of crisp nights and warm, sunny days.
Slow southeasterly winds will keep overnight lows between +4 and +9 degrees Celsius, while daytime highs will hover between +17 and +22 degrees. As usual, coastal temperatures will be a degree or two warmer than inland.
However on Sunday clouds will begin gathering over western Kurzeme province, heralding the arrival of a cyclone system from Scandinavia. The cyclone’s exact development and direction cannot be accurately forecast, but meteorologists say that cooler, wetter weather is a certainty.
The extreme end of the forecasts could see an arctic air mass flow down over Scandinavia and the Baltic, bringing the first wet snowfall accumulations to regions north of Latvia.
While not expected to wind up under the possible snows, Latvia may expect strong winds, thunderstorms and large amounts of precipitation in the form of rain and hail.
Temperatures may also dip quite sharply and suddenly, with daytime highs by Tuesday limited to just +10 degrees.
Amidst the warnings of next week’s possible inclemency, readers should note that a kinder, gentler forecast has also been formulated, which calls for the arctic air mass to stay farther north, meaning less extreme precipitation and warmer temperatures for Latvia on Monday and Tuesday.
