Forecast Insight For Tuesday, October 20, 2009

Today:

Synopsis of Weather Conditions:

Today an area of high pressure centered to our east will continue to drive the forecast. The result will be a southerly wind and plenty of sunshine that will carry the temperature up to around 70 degrees. While it may be breezy at times this afternoon, winds won’t be as intense as they were yesterday.

Forecasted High Temperature

Today’s Wind Forecast: South-southwest winds at 5 to 15 mph…


Tonight:

Synopsis of Weather Conditions:

Tonight we will continue to see mainly clear skies thanks, again, to the influence of high pressure. Dew points overnight should be in the lower 40’s or upper 30’s preventing the temperature from getting much cooler than the mid 40’s. In fact, the more I mull over tonight’s potential low temperature, the more I think the majority of the tri-state will only get down into the upper 40’s, but the clear skies and weak winds are reason enough to maintain a forecast low of 45 for now. Frost will not be a concern for tonight.

Forecasted Low Temperature

Tonight’s Wind Forecast: South winds at about 3 mph… Otherwise, expect calm winds…

Tomorrow:

Synopsis of Weather Conditions:

Tomorrow we should start out with plenty of sunshine, but high clouds will start to build across the viewing area as soon as tomorrow morning. The high clouds are leading an advancing storm system to our west that will eventually bring rainfall to the tri-state beginning either Wednesday night or Thursday. That said, Wednesday will be staying rain-free. Some models are indicating tomorrow’s high temperature could actually be cooler than today’s, but I think those models are taking the effects of building cloud cover too much into play. While I think we’ll see enough sunshine during the morning and afternoon hours to see that temperature rise into the upper 60’s and lower 70’s region-wide, I would not be surprised if the skies turned mostly cloudy or overcast by sunset. With all this talk of cloud cover it sounds like tomorrow could be a drab day, but the reality is that high clouds typically play a limited role in diminishing sunshine. Overall, Wednesday will probably be the last beautiful day until next week.

Forecasted High Temperature

Tomorrow’s Wind Forecast: South winds at 5 to 10 mph…

Extended Forecast Overview:

*What someone deems to be unseasonably warm or unseasonably cool is entirely subjective and also depends on the typical temperature variability of any given location. For the purposes of the chart above, unseasonably warm will be defined as having a high temperature greater than 10 degrees above the seasonable average for that day at KEVV (The Evansville Regional Airport). Likewise, unseasonably cool will be defined as having a high temperature 10 degrees below the seasonable average for that day at KEVV.

**It’s important to note that Ron’s temperature forecasts may significantly differ with the other forecasts from time to time. There are two reasons for this. First, Ron is working with older model data than myself when I come in during the morning hours and produce my forecast. Model forecasts can vary significantly between issuances. Second, Ron may see reasonable meteorological evidence to vary his forecast significantly from the models and myself. His forecast is added to the temperature forecast grids to provide additional perspective into the forecast.
