3/20 – Rob Knight’s “First Morning Of Spring” Forecast

0

A high moisture content corridor continues to move in from the south. With an approaching cold front, this should produce a decent chance of convection and subtle compressional heating between converging boundaries this afternoon. Cold high pressure building out of Canada shunts eastward rather quickly to elongate the boundary over the forecast area tonight, thereby causing the attendant moisture to diverge towards daybreak Saturday. Models show gulf breeze process to augment the frontal zone on Saturday’s daytime heating.

Once again, pronounced area of showers and thunderstorms likely to develop in this scenario for Saturday afternoon through Monday afternoon. The long range portion of the forecast period will feature evolution of upper pattern from zonal to ridging over the Gulf of Mexico while troughing takes place over the Pacific coast. Large scale subsidence should suppress rain chances for middle of the week along with a steady warming trend that may see near record high temperatures by Thursday or Friday in interior sections.
