REVIEW OF PREVIOUS FORECAST
Nailed the HUX forecast yesterday. With easterly wave passing to the south,
convection fired north and northeast during the day, clipping us by late in the
afternoon as predicted (kudos to Pete Black for pointing out this behavior
during the passage of the previous wave...). Would be interesting to examine
individual storm motion in a coordinate system relative to the wave phase
velocity....
GENERAL OVERVIEW
95W under clearing skies today after passage of wave disturbance
yesterday (Image 1). Still looks like we will have a series of easterly waves
moving thru the next week or so. This am, an area of convection is
found near 5n, 83w - not sure if this is associated with a wave and is a
bit south of normal. Will have to watch this during the day to see if
it holds together. Think this convection may actually be associated with vort. center
that Wisc. analysis shows further east in western Carib. near 78w (Image 2).
This may have actually jumped over central america already.
Upstream, next wave is found at 12n, 72w but expect
this will get steered into EPIC area the next few days as upper level
cloud and wv winds continue to show flow from east-northeast over western
carib (Image 3). Not much else upstream in the Atlantic.
DISCUSSION
Will be interesting to see if we can track easterly wave now at 65w 11 n
across into EPIC area or not...this still holds for today....
SUMMARY
Looks like we have the P3 for some time...need to get more dropsondes for it
Tues - no flights
Wed - C130 95w flight; P3 no flight
Thurs - ITCZ flight both a/c
Fri - P3 - depending on wave passage
Sat - C130 95w, P3 ocean probe
