MM’s Tues Wx Forecast for Aug 30

Ice crystals in a distant cirrus cloud are acting like little floating prisms. Known informally as a fire rainbow for its flame-like appearance, a circumhorizon arc appears parallel to the horizon. The numerous, flat, hexagonal ice-crystals that compose the cirrus cloud must be aligned horizontally to properly refract sunlight in a collectively similar manner. Therefore, circumhorizontal arcs are somewhat unusual to see. The featured fire rainbow was photographed last August near North Fork Mountain in West Virginia by Christa Harbig.

Wx Summary

A frontal system will bring scattered showers and thunderstorms to the area today. Some of those storms could produce heavy rainfall. The front should clear the area by late this evening, setting the stage for a very pleasant Wednesday and Thursday, with low humidity and comfortable afternoon highs. Heat and humidity begins returning by Friday, bringing back a slight chance for isolated afternoon storms on Friday, followed by scattered showers and storms for Saturday.

Past 24-Hour Precip Totals 

Hurricane Forecast

Two areas of concern will likely evolve into the next two tropical storms for the Atlantic. Those storms are expected to develop over the next 48-72 hours. Neither one pose a threat to the US at this time, and there are indications that both systems may stay out at sea. Nevertheless, both bear watching over the coming week.
