A high-pressure system will set the weather pattern for the week, with mostly sunny skies, few clouds and no precipitation predicted. Winds are forecast to be slow, with nights almost at a still calm.
But overnight temperatures are expected to nudge toward lows near zero, threatening the chance of frost across the land, especially from Tuesday to Wednesday.
And daytime highs should stay between the cool range of +13 and +19 earlier in the work week, but reaching from +20 to +22 during the day on Thursday.
While the winds will pick up from the south-southeast Friday, high temperatures will rise more to between +20 and +25, though still cooler on the coasts.
There is finally the promise of some proper summer heat on the weekend days, but that will bring with it some accompanying thunderheads, say weather observers. Nighttime lows will finally stay in the teens between +13 and +17 and on Saturday highs will be from +23 to +25 and on Sunday possibly reaching +30 degrees in some places.
