REVIEW OF PREVIOUS FORECAST

Persistence worked well yesterday.  For the second time, we saw the mountain
showers move over HUX in the evening as strong NErly flow continues aloft and
trough remains deep into Gulf of Mex.

GENERAL OVERVIEW

EPIC area under the influence of re-building ITCZ and deep mid-latitude trough.  ITCZ re-building nicely 
today from 97W back to coast of central america and from 6-9N (Image 1).  Good Cb activity found all along this 
region and cyclonic vorticity apparent (Image 2).  95W line effected by deep mid-latitude trough extending into bay of 
Campeche forcing flow across Isthmus of Tehuantepec resulting in cyclonic shear line and Cb activity along 
95W from Mexico south to 8N.  This deep trough forecast to remain stationary for the next 96 hours, so 
persistence (en espanol, manana manana) is the forecast for the next several days.




DISCUSSION

NWP models showing deep 500mb trough in Gulf of Mex to persist thru 96 hours.
So, will go with persistence - manana - as the forecast.

SUMMARY

Given the number of days left versus the number of flight hours and required down days, Dave Raymond has 
posted this tentative schedule for flights thru the end of the HUX operations:
