Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 306 AM EDT Mon Mar 18 2019 Valid 12Z Mon Mar 18 2019 - 12Z Wed Mar 20 2019 ...Heavy rainfall possible along a lingering frontal boundary across southern Florida... ...Major to historic river flooding will continue across parts of the Mississippi and Missouri River Basins... ...Warm temperatures and snow melt may lead to areal flooding across portions of the Northwest and Northern/Central Rockies... The weather will continue to be fairly quiet across most of the lower 48 during the short range period. The exception to this will be across southern Florida where locally heavy rainfall is possible along a lingering frontal boundary Monday into Tuesday. Elsewhere, light rain or snow is possible by Tuesday from parts of the central/southern Plains into the mid-Mississippi Valley; and increased precipitation chances out West by Wednesday as a cold front approaches California. Most locations from the Rockies eastward will be dominated by surface high pressure which will keep temperatures near or below normal for this time of the year. The greatest departures from normal (10 to 20 degrees) are forecast across parts of the southern Plains as well as the Appalachians into the East. Major to historic river flooding is expected to continue across parts of the Missouri and Mississippi River Basins due to rapid snow melt the past few days. Flood warnings and advisories remain in effect, mainly across eastern Nebraska and into parts of Iowa. Flooding is also a concern across parts of the Northern Great Basin into the Northern/Central Rockies as warmer than average temperatures lead to accelerated snow melt for the lower elevations.
