Early Ag Weather Watch - Feb 24
EARLY LOOK WEATHER REPORT
NATIONAL TEMPERATURE/RAINFALL EXTREMES:
HIGH SUN...89 AT DRYDEN TX
LOW SUN...8 BELOW ZERO AT FERGUS FALLS MN AND FOSSTON MN
24 HOUR RAINFALL ENDING AT 06:00 PM CT...DAYTONA BEACH FL 0.98 INCH
US OUTLOOK AND MODEL DISCUSSION:
The US and European models are in fair to good agreement during the next 5
days, fair agreement during days 6-10. I am using a compromise between the
models as it concerns the 6-10 day period. The main problem area during the
6-10 day period is in how much trough moves across the southern plains and
lower Miss river valley and how fast this trough may move. The US model is
somewhat deeper and slower moving with this trough and therefore has more
precipitation associated with it. In either case the short range maps feature
extreme cold and only light or locally moderate precipitation chances. Also in
either case there is some chance for precipitation and less cold for the
southeast plains, the lower Miss and the Ohio river valleys during the 6-10 day
period. In the case of the US model this chance may also include the southwest
plains region as well. The high latitude blocking ridge was shown over Alaska
last evening. The long range maps, days 8-10, show this ridge west of Alaska.
The strong jet stream dips fairly far to the south early in the ten day period.
Later in the period the jet stream is somewhat split with one branch moving
west to east over the northern US and a second jet stream moving across the
southern plains and the Delta before merging with the northern branch over the
northeast US region.
MAJOR WORLD HIGHLIGHTS/IMPACT:
SOUTH AMERICA: The upper level ridge is over east-central Brazil and in the
Atlantic today. Troughs are west of central Chile and over southeast Argentina.
The forecast shows the ridge remaining mostly in place through the middle of
this week. The Chile trough and the Argentina trough gradually merge over
southern Brazil later in the week. This causes an eastward shift to the ridge
center this weekend and early next week. This may allow some shower activity to
reach into the drought areas of Minas Gerais but this is somewhat uncertain.
ARGENTINA: A drying trend is expected during this week. This will favor
developing crops, after recent heavy rains. Cool weather early this week gives
way to warmer weather late in the week.
BRAZIL SOYBEANS/CORN: Heavy thunderstorms during the weekend for portions of
Mato Grosso and Parana likely means local flooding and delays to field work.
This may include harvest delays for soybeans and first crop corn and delays to
planting of second crop corn. Soil moisture for filling crops is adequate to
surplus at this time.
BRAZIL COFFEE, CITRUS, SUGARCANE AREAS: The drought pattern is expected to
continue for Minas Gerais crop areas for much of this week. There appears to be
at least some chance for increasing shower activity during the weekend and
early next week. If verified this would help ease stress to crops but there is
some uncertainty in this outlook. There appears to be a somewhat better chance
for needed rains to occur in Sao Paulo crop areas next weekend and early next
week.
CENTRAL/SOUTH PLAINS: A return to colder weather is expected in the north and
east U.S. during this week. This appears to be mostly outside of the plains
wheat belt but it will bear watching.
MIDWEST: Extreme cold returns to the region, departures from normal at least 15
to 25 degrees below normal...possibly colder. Soft Red Winter wheat is somewhat
at risk since the recent warm spell has melted protective snow cover. Extreme
cold will again dramatically increase the usage of Natural Gas for heating. No
major transportation delays due to weather during the next 5 days.
SOUTH AFRICA: Scattered weekend showers will help to maintain favorable
conditions for filling maize and sugarcane crops in the region.
CHINA: Moderate to locally heavy snow and rain has occurred through central and
southern winter wheat areas of eastern China and through most winter rapeseed
areas during February. This will help to replenish soil moisture and it will
favor crops when they break dormancy in the spring. Snow to the north was not
as heavy but still fairly significant for this time of the year. Snow and ice
and to a lesser extent rain will have delayed transportation somewhat. The
weather pattern currently favors additional chances for snow or rain through
the Yangtze river valley and the southern part of the North China Plain.
