Saturday\u2019s Weather

\"\"

The evolution of the east coast Low Pressure is complicated with an extended frontal boundary from Florida to Maine on Saturday with major impacts.

South Florida Deluge Next 3-Days

\"\"

Rainfall forecast amounts have decreased this morning a little bit especially around Miami, now expected 3\u201d to 4\u201d rather than upwards of 6\u201d. However, the squalls coming off the Gulf of Mexico will be localized and difficult to pinpoint exact amounts.

\"\"

Thursday: Low pressure system over Northeast and Maritime Canada deepens with significant snowfall in Maine into Canada.

Friday into Saturday: area of low pressure skirts along Gulf Coast = heavy rain for Florida, 3-5\u201d. All of that moisture across the Southeast surges up the East Coast

Saturday into Monday: Another storm system landfalls the West Coast with a 996 mb low pressure off Oregon bringing Pacific moisture onshore.

East Coast frontal boundary develops a low pressure system and intensifies with heavy rain in Mid-Atlantic and Northeast, and heavy snow again in northern New England.

Monday: Powerful central plains into Midwest winter storm still in the forecast with Minnesota the locus of upwards of 2-feet of snowfall.

Next Wednesday and Thursday: West unsettled again with boatloads of Pacific moisture arriving within a very chilly trough/ weather pattern, to considerable mountain snowfall.
