For the forecast, a strong warm front in this active series of systems will bring heavy precipitation and strong winds to our zone this morning into tonight in a Southwest flow. Freezing levels will rise to about 1300 meters by tonight, which is much cooler than the last front. The next strong frontal wave will arrive on Sunday with a slightly higher freezing level of around 1400 meters. Monday is looking slightly warmer, FL around 1600 meters max, with light precipitation. Tuesday is looking like another fairly strong front with a FL hovering around 1500 meters. Wednesday will be unsettled with cooler temperatures. Guesstimates: 20-30 cm by Sunday morning, 30-40 cm by Monday morning.

    Deepening low will bring precipitation to the area this am.

    Unfortunately it is a warm front with strong winds for today into this evening.

   A series of strong frontal systems for Sunday, Monday, Tuesday with breaks in between.

    Low will still be pumping moisture at us into Wednesday.
