Spring fever has spread across the country....literally. High temperatures will be in the 70s from California to Denver to Washington DC. Only the northern tier of States will remain relatively cool and the only snowfall in the lower forty eight will be in the mountains of the Pacific Northwest.
This first major outbreak of spring warmth is brought to us by the jet stream, as usual. These steering winds are flowing west to east across southern Canada, protecting us, for a few days at least, from any Arctic air. By the end of the week, the jet will drift southward, bringing back more seasonal conditions and restoring our sense of reality. Afterall, it is March.
