Although it will be cloudy, not much rain is expected. However, as the week wears on, showers are forecast, while temperatures are forecast to rise.

After another frosty night with temperatures as low as -5 degrees Celsisus in the Northeast, Wednesday morning will be mostly cloudy, though with no rain and only very light southerly breezes. Fog may remain early in the morning so care should be taken when driving.

Ambient temperatures will be similar to those of the previous night: Minus 5 degrees in the Northeast, -3 on and near the shores of Peipsi järv, and -1 degree across the rest of the country.

Temperatures will get milder during the day, up to +4 degrees in Tallinn, much of North and central Estonia, and on Saaremaa, and up to +5 degrees in the Southeast. Western Estonia will be chilliest at +2 degrees.

The cloud cover will continue during the day, and even give rise to patches of showers, particularly in the Tallinn area.

Milder conditions are forecast through to St. Patrick's weekend, bringing some suitably soft weather. Showers are forecast, potentially falling as sleet when temperatures are lowest, for instance overnight Saturday to Sunday

On the other hand, mean temperatures will continue to rise and values in the minuses will more or less disappear nationwide.

Daytime temperatures will be between 3 and 9 degrees Celsius, and as high as -12 degrees on Saturday and Sunday, while nighttime averages are set to rise from +2 degrees on Wednesday night, to +5 degrees Friday night to Saturday morning.

Sunday is set to be a little colder, however.

At present and through to March 21, the vernal equinox, the rate at which the days are getting longer (by five minutes and 21 seconds per day, to be precise) is at its peak. Thus, whereas dawn today, Wednesday, came at 6.42 a.m., on Sunday it will fall at 6.30 a.m. Similarly, sundown on Wednesday is at 6.19 p.m., compared with 6.29 p.m. on Sunday (Tallinn times).
