New Weather Math experiment. new indexes. feedback please.
Posted: Mon Aug 18, 2003 4:28 pm
This is an Experimental Project for these areas only. This is for today, August 18th 2003. The
descriptions show the percent of severe potential. 100% being the most it can get, 0% being the least.
at the bottom of each column, it shows a line of numbers with percents. some have a plus sign , and
some have a negative sign. the plus signs show that that severe ingredient MUST BE THERE. at the end
I add up every positive percent, and come up with a percentage. i think take that percentage and
divide it by the most possible percentage of all 6 positve ingredients. I then get the number of
possible severe weather for the day for that area.
========================================================================================================
NEWEST ADDITION TO THE FORECASTING IS CAPE, HELICITY, SHOWALTER INDEX, CONVECTIVE TEMP, BASE LEVEL FOR
T-STORMS, LIFTED INDEX, TOTAL TOTALS, AND SWEAT INDEX OR Severe Weather ThrEAT. Hope you like it.
Eastern Arizona/New Mexico Border.
The air will need moisture content today. 25% YES
The temperature will be 78 degrees with a 55 or higher dewpoint, the air will be fairly unstable. 40% YES
With the 850MB winds being at 19 knots , ill defined Low Level Jet is in place. 20% YES
Southeast Wind at the Surface-NO, Southwest wind at 700MB-YES, Northwest Jet at 300MB-YES
Jet stream Winds at 19 knots, for Small Divergence. 20% YES
500MB winds show Low But Positive Divergence. 20% YES
CAPE INDEX will be marginally unstable. 20%
SWEAT INDEX will be 150 or unlikely. 20%
LIFTED INDEX will be at +2 or stable. 20%
SHOWALTER INDEX will be 1 to -2. 42%
HELICITY INDEX shows NO tornado formation will happen.
TOTAL TOTALS are at 49-50. 67.5%
OUTLOOK for Northeastern Arizona/New Mexico Border storms today.
THE POSITIVES MEAN THAT FACTOR MUST BE THERE FOR SEVERE THUNDERSTORMS. THE NEGATIVE, NOT NEED BUT HELPS

The Convective Temperature will be around 88 degrees.
But since this area is in the mountains, the Convective temp will not be needed.

TUCSON AREA SEVERE STORM POTENTIAL
The air will be Semi Juicy today. 50% YES
The temperature will be 97 degrees with a 55 or higher dewpoint, the air will be Extremly unstable. 80% YES
With the 850MB winds being at 26 knots , a ill defined Jet is in place. 20% YES
Southeast Wind at the Surface-NO, Southwest wind at 700MB-YES, Northwest Jet at 300MB-YES
Jet stream Winds at 14 knots, for Small Divergence. 20% YES

Since the Convective temperature meets the actual temp for today, expect convection all around this
area today.
========================================================================================================
PHOENIX AREA STORM POTENTIAL
The air will be Semi Juicy today. 50% YES
The temperature will be 105 degrees with a 55 or higher dewpoint, the air will be incredibly unstable. 100% YES

Since the Convective Temperature might fail to reach the surface temperature for today, Convection will
probably NOT happen at all today in, or around this area.

Tucson, and the Eastern Arizona/New Mexico Border will most likely be the worst storms today.
the further east you go, the Tougher storms you'll get.
