Warmest Day of the Year So Far?
Matt Ross @ 1:00 AM
Temperatures 20 degrees above average today will moderate a bit on Wednesday as the ebbs and flows of March continue.
Some Clouds, Very Warm. Today will be partly sunny with a slight chance of an isolated afternoon shower or thunderstorm. A stiff westerly breeze will help our afternoon temperature to climb to near 80 degrees. We have about a 50-50 chance of matching or eclipsing our highest temperature so far this year of 81 recorded on March 14th.
Partly Sunny, Cooler. Tonight will be partly to mostly cloudy with overnight lows in the lower 50s. Wednesday will see winds shift to the northeast with a slight chance of afternoon showers, mainly in the southern suburbs. We will have partly sunny skies with afternoon highs in the mid to upper 60s. Refer to Jason's forecast for the rest of the week and weekend.

Leading up to the very cold February of 2007, 15 out of the previous 20 months had above average temperatures. It now looks like March will finish slightly above average and it would not surprise me if we return to form and run off several above average months in a row.
While El Nino-Southern Oscillation(ENSO) is only one part of the equation, there is little doubt that the Equatorial Pacific has a big impact on our weather. The La Nina that looked like it might rapidly develop in February has slowed to a halt over the past 6 weeks as sea surface temperatures have hovered around normal. As indicated by the above map, past years that have had similar ENSO profiles in the late winter and early spring, have often, though not always, led to above average temperatures in the spring and summer. If this tendency repeats itself this year, it could make for a very pleasant April-May period followed by a not so pleasant summer.

Another Warm Streak for Summer and Fall?
