Stable freeze-over setting in?

The weather this week is set to gradually dip into the dreaded ‘naked-freeze’ territory in some parts of the land where the snow cover has all but disappeared, warned LSM meteorologist Toms Bricis Tuesday.

However, frost and frozen fog are possible winter weather phenomena to look for in the early mornings. The chance for precipitation in the form of snow is quite low this week, besides some flurries.

Overnight low temperatures to Tuesday were already way below freezing at -10 degrees Celsius in places deeper inland in the provinces of Latgale and Vidzeme, whereas near Riga and western Kurzeme lows were between -2 and -5 degrees.

While daytime highs may rise to just above freezing at +1 degrees, a steady mild wind from the south east may nevertheless reach up to 14 meters per second on the horn of Kolka. The high in Rīga is expected to be around -1 degrees.

The weather for the extended forecast is being determined by the southwestern edge of an anti-cyclone, so the atmospheric pressure has risen to 767-771. This should bring the temperatures down to below zero on a consistent level for the next few days, say forecasts.

Combined with the lack of snow cover in some parts of the country, it is possible that freshly sown fields of winter crops can suffer damage without protection from the ‘naked freeze’ on the ground.
