FORECAST IN DETAIL
A surge of summer aims for our area today through Thursday with temperatures attaining the 90s along with moderately unpleasant humidity. Getting 90s in September is not unusual (record highs are in the low-to-mid 90s into the first third of October too). September 24, 2010′s 99F is the hottest reading so late in the month! But with everyone looking toward autumn, the heat is a reminder that summer is not too far back in that rear view mirror yet.
Relief comes following Thursday’s clouds and p,m. storm chances. Dramatically cooler weather arrives Friday and the weekend.
Today (Tuesday): Some gray overcast continues into the morning with a much better chance for some sunshine in the afternoon. Winds from the south and southwest at 5-10 mph fuel our area with higher humidity (dew points creep up to the middle to upper 60s) as highs push into the upper 80s and low 90s. The humidity makes it feel like the middle 90s at the peak heat of the day. Confidence: Medium-High
Tonight: Partly cloudy and muggier as lows drop only in the upper 60s to low 70s (warmest in the city). The air conditioners will need to keep running tonight! Winds from the southwest at 5 to 10 mph. Confidence: Medium-High

Tomorrow (Wednesday): Our hump day is the hottest one of the week with highs in the low to middle 90s along with moderate to maybe high humidity levels. If the humidity underperforms (a distinct possibility due to our drier soils right now), we could have high temperatures push higher into the middle to upper 90s instead. Winds from the southwest at 5 to 10 mph again. Thunderstorm chances are reserved mainly for the mountains (25 percent chance there). Confidence: Medium-High
Tomorrow night: Partly to mostly cloudy with light winds and heavy humidity as lows only drop to around 70 or hold in the low-to-middle 70s in the city. There is a 20% chance of a scattered shower or roving thunderstorm. Confidence: Medium
A LOOK AHEAD
Thursday is still on the hot and humid side, but more clouds and thunderstorm risks in the afternoon should prevent highs from being as hot ahead of a big cold front. We currently expect low 90s by early afternoon with clouds and rain chances by mid-to-late afternoon. We currently have a 40% chance of showers and storms, but that may increase as we get closer and more confident. The cold front passes through Thursday night along with a 30% risk of scattered showers and storms yet. Temperatures fall to the more comfortable low to middle 60s toward dawn. Confidence: Medium
Friday features a fantastic flip from the heat with highs only in the upper 70s as winds from the north bring down a much more comfortable and less humid air mass. Skies are partly to mostly sunny as the front gets farther from the area. Turning much cooler Friday night with just a few clouds and lows dropping into the low-to-middle 50s. Confidence: Medium
The weekend stays cool with highs in the 70s and lows in the 50s. There may be a few more clouds around on Saturday vs. Sunday with a weak disturbance, but still a fairly pleasant weekend is expected due to comfortable temperatures and sunshine opportunities, especially on Sunday. Confidence: Medium-High
