I don't know about you, but I'm ready for winds to wane and temperatures to stay mild. But, we're still in this spring back-and-forth, at least for now it seems. Under plenty of sunshine, highs mainly into the mid-60s have warmed slightly since yesterday but they do feel occasionally chilly thanks to a still gusty wind from the northwest. Tomorrow we'll remain well below our current average highs in the mid-70s before popping above on Wednesday.

Through Tonight: High clouds gradually enter the picture before they begin to thicken and lower toward morning. Evening temperatures fall to the upper 50s and low 60s around sunset before heading for lows near 40 in the colder suburbs to the mid-or-upper 40s downtown. Winds subside to light as the night progresses.

Tomorrow (Tuesday): Showers and thunderstorms that are part of a system likely to spawn a tornado outbreak in the plains today and tonight rapidly shift east toward the area tomorrow. We'll be on the north side of a warm front though and cool temperatures, only rising to the upper 50s or near 60, should help weaken the storms as they arrive by afternoon. Nevertheless, some beneficial showers and a few rumbles of thunder may continue through around midnight.

Severe weather: A "high risk" of severe weather, including long-tracked tornadoes is underway in parts of Oklahoma, Kansas and surrounds. VORTEX2, a two-year government project to study tornadoes, recently began its 2010 operations and this could end up being a pivotal day for their research. CWG's Andrew Freedman joined up with the team last year for one of the only successful chases during a relatively quiet season.
