Hi,
NCEP requests two flights to be flown around 012300, track numbers
1 and 45. These will be the first targeted flights this season over the
Pacific.
Dropsonde data collected along track #1 are to imporve forecast around
012400, around 60N 150W (heavy precip event).
Dropsonde data collected along tracks #1 and #45 are to imporve forecast
around 012600, around 30N 90W (possible heavy precip), and for a possible
east coast storm following
that.
OUTLOOK: A flight with the G-lV is possible around 012400 (#20 or similar
track). No flight with the C-130 that day.

FLIGHT REQUEST FOR 012400: No flight is requested
OUTLOOK FOR 012500: Possible flight with C130, possibly
track #46. Probably no flight with G-lV.
OUTLOOK FOR 012600: Possible flight with G-lV, track
#23
COMMENTS: Most sensitive area for possible east coast
storm around 012700 is over land (Alaska). C-130 is not available for use
to cover secondary sensitive area.
Zoltan
FLIGHT REQUEST FOR 012500: A flight with C-130
from Portland to
Honolulu with a turning point at 30N 132.5W, sounds should be dropped
about every 30 minutes with the first sound dropped once the
aircraft
is offshore
OUTLOOK FOR 012600: Possible flight with G-IV, possibly track #23.
COMMENTS: The flight with C-130 will target the most
sensitive area
for possible east coast storm around 012700/12, at 37.5N, 75W.
Istvan Szunyogh
FLIGHT REQUEST FOR 012600: NCEP requests a flight with the G-lV out of Anchorage, track #23. No flight with the C130.
OUTLOOK FOR 012700: A flight with the G-lV is possible, but not likely. Currently we do not plan on using the C130 on this day.
COMMENTS: The flight around 012600 will provide data to improve forecasts for heavy precipitation events over Alaska, around 012700, 60N 150W, and 012800, 60N 145W
Zoltan
FLIGHT REQUEST FOR 012700: No flight is requested.
OUTLOOK FOR 012800: A flight with both the G-lV (track # 19 or 20) and the C130 (track # 37 or 45) is probable.
COMMENTS: None.
FLIGHT REQUEST FOR 012800: NCEP requests a flight with both the G-lV (track #20) and the C130 (track #45).
OUTLOOK FOR 012900: Possible flight with the G-lV (track #20 or 21)
OUTLOOK FOR 013000: Possible flight with C130 (track #37)
COMMENTS: The 012800 flights collect data for imporving
the weather forecast for a possible east coast snow storm (013112, 37N
, 75W) and for a west coast precipitation event (013000, 50N, 125W). The
data will also have an impact on the precurser of the east coast
storm (013000, 32N, 82W).
REQUEST OF CHANGE FOR 012800: NCEP requests to change the flight track
for G-IV from #20 to #17
FLIGHT REQUEST FOR 012900: No flight is requested.
OUTLOOK FOR 013000: Possible flight with C130 (track #37)
COMMENTS: Flight track #17 provides a better coverage than
#20 of the
most sensitive area for the west coast precipitation event (013112
45N/125W), while the two tracks provide equally good coverage for the
possible east-coast snow storm (013100/12, 38N /77W).
Istvan Szunyogh
FLIGHT REQUEST FOR 013000: NCEP requests flights with both airplane.
The
flight track for the G-IV is #21 and the flight track for the C-130
is
#37.
OUTLOOK FOR 013100: If the flights for 01300 will be cancelled a possible
flight with the C-130 (track #36)
COMMENTS: The flights will cover the most sensitive area for the possible
west coast precipitation event (snow in the mountains of northern CA;
020100, 45N, 125W). NCEP may cancel the two flights for 01300 if HPC
downgrdaes the high priority of the event tomorrow morning.
Istvan Szunyogh
Addendum, Jan 29: The flights around 013000 would also provide data
for the precurser of a possible east coast storm around 32N, 90W around
020300.
FLIGHT REQUEST FOR 013100: No flight is requested. We request, if possible, that the C130 plane, on its direct route from San Fransisco to Honolulu (take-off around 01302000), release dropsonde data approximately every 30 mins east of 145W, and every 60 mins west of 145W.
OUTLOOK FOR 020100: No flight is likely with the G-lV.
We request that if possible the C130 plane that flies from Honolulu to
San Fransisco (take-off around 01311900) carries out a mission, by flying
through the following two waypoints:
Honolulu
40N 155W
45N 135W
San Fransisco
Dropsondes should be released approximately every 30 minutes.
COMMENTS: The dropsondes released around 013100 should
have some impact on the forecast precipitation event verifying around 020100,
around 40N, 112W, thought the flight follows a direct track from SF to
Honolulu and therefore the dropsonde locations are not optimal. The possible
mission around 020100 would target sensitive areas for a west coast heavy
precipitation event (moderate priority), verifying around 020200, around
45N, 125W, and for a possible east coast winter storm (high priority),
around 020400, around 32N 87W.
FLIGHT REQUEST FOR 020100: No flight is requested
with the G-lV. We
request that if possible the C130 plane that flies from Honolulu to
San
Fransisco (take-off around 01311900) carries out a mission, by flying
through the following two waypoints:
Honolulu
40N 155W
45N 135W
San Fransisco
Dropsondes should be released approximately every 30 minutes.
OUTLOOK FOR 020200: Possible flight with the G-IV (track #23 or #24)
COMMENTS: The mission around 020100 targets
sensitive areas for a
west coast heavy precipitation event (moderate priority), verifying
around 020200, around 45N, 125W, and for a possible east coast winter
storm (high priority), around 020400, around 32N 87W.
Istvan Szunyogh
FLIGHT REQUEST FOR 020200: NCEP requests that a C130
scheduled to fly from San Fransisco to Honolulu around 020200 carry out
a mission, flying through the following waypoint:

Honolulu
Sondes should be released approximately every 30 mins.
No flight with the G-lV
OUTLOOK FOR 020300:
No flight is expected with either plane.
COMMENTS: The flight around 020200 is in support of
a northern plane winter storm event around 020412, around 42N, 102W. It
will also provide initial data for a precipitation event around Florida,
27N, 80W, around 020412.
FLIGHT REQUEST FOR 020300: No flight is requested.
OUTLOOK FOR 020400: Possible flight with the C130, no flight is likely with the G-lV.
COMMENTS: There is no major weather system in the
forecasts today.
FLIGHT REQUEST FOR 020400: We request a flight with the C130 around 020400, track number 37.
OUTLOOK FOR 020500: No flight is planned with either the G-lV or C130.
COMMENTS: The flight around 020400 is to collect data
to support the forecast of a precipitation event around 020512, 37N 125W,
and 020600, 37N, 122W.
FLIGHT REQUEST FOR 020500: No flight is requested.
OUTLOOK FOR 020600: Possible flight with the C130 (track number 37 or similar); no flight is likely with the G-lV.
COMMENTS: No major weather system is in sight.

FLIGHT REQUEST FOR 020900: NCEP requests a flight with the G-lV, track # 20. This is the last mission with the G-lV this season.
OUTLOOK FOR 021000: No airplane is available.
OUTLOOK FOR 021100: We consider flying with the C130, #37 (or similar) track.
COMMENTS: The 020900 flight is designed to reduce uncertainty of a fast moving storm, and a possible follow up wave across the eastern US: around 021112, 40N, 95W, and 45N, 75W; 021212, 45N, 75W. This is a high priority case. The position of the low(s) is, however, very uncertain and the data can have a large impact over the eastern US between 021100 through 021300.
NOTE: The C130 will not be available until 021100.
NCEP requested that, if possible, the USAF extend their WSR2000 mission
a couple of days beyond the original plans (which had 021200 as the last
possible flight day).
FLIGHT REQUEST FOR 021000: No plane is available.
OUTLOOK FOR 021100: We expect a flight with the C130, #36 or similar track
OUTLOOK FOR 021200: No flight is possible if 021100 flight takes place
OUTLOOK FOR 021300: Possible mission with the C130 in case the plane would be available
COMMENTS: None

a couple of days beyond the original plans (which had 021200 as the last
possible flight day).
FLIGHT REQUEST FOR 021100: NCEP requests a flight with the C130, track # 37
OUTLOOK FOR 021200: If the 021100 flight takes place, no flight is feasible. If the 021100 flight is canceled, we may want to fly around 021200.
OUTLOOK FOR 021300: We request, if possible, a flight with the C130, probably track # 37 or 46.
OUTLOOK FOR 021400: No flight is possible.
OUTLOOK FOR 021500: We request, if possible, the C130 carries out a mission on its way to the west coast.
COMMENTS: The flight around 021100 is to collect data to
improve forecasts for a precipitation event around 021200, 37N, 122W; and
for an east coast storm, around 021300, 40N, 80W.
The flight around 021300 would collect data to improve forecasts for
heavy precipitation events along the west coast, 021400-021500, 37N, 122W;
and for a possible east coast winter storm around 021512, 37N, 75W.
