The outlook for March, April and May-- in the mean-- not every day or every week is for warmer than normal temps and near-average to below-average precipitation for the 90-day period in the mean. But before then another 2-4 weeks of up and down and back and forth like we've seen since September with warm spells and cold snaps alternating. So it's below-normal March, above-normal temps April and May.
This active jet stream pattern or "progressive regime" keeps the fronts and low pressure systems coming so we stay in the wet drought relief pattern through March. As long as we can keep any serious flooding at bay this will be welcome. But remember my old maxim: most droughts end in floods and most floods end in drought. Several close calls with snow in Atlanta this winter, and several real snows in the mountains. The snow window for Atlanta is not shut tight just yet, but its open just a crack. The models are hinting at a pattern favorable once again for some mischief from Old Man Winter early in March and maybe thrugh the 20th or so, but it's too early to tell if the pattern potential will come up empty again in Atlanta or be fullfilled. The snowstorms look centered on the Great Plains and Midwest to Great Lakes, with some out West and some in the Northeast US.
Highest odds for warmer and drier than normal the next 90-days look to be in the Southwest US and the central plains. The spring severe weather season here in the SE looks about normal with GA on the edge between a more active than normal severe season just west and north of here and a less active season east and south of here.
