...Record High Temperatures Across West Michigan on February 18th 2017...

February 18th will be a special day in the climatology of West Michigan, as
many locations set new daily high temperature records.  Several sites also
saw their 3rd or 4th warmest high temperatures ever recorded in February.
Lansing`s high of 65 degrees today not only broke the previous daily record
of 56 degrees set in 2011, but it was also the 3rd warmest high for Lansing
on record for the entire month of February(Lansings records date back the mid
1860s).  Jacksons 66 degree high today broke the daily record high of 59 degrees
set in 1976 and is also the 3rd highest for Jackson for the month of February.
Jacksons records go back to 1944.  Kalamazoos 66 broke the record of 57 set
in 2011 but are also third highs on record for February at Kalamazoos,
however records there only go back to 1998.  Battle Creeks 66 degrees broke
the daily record of 57 degrees set in 1961 but is tie for 4th place with 1930
for the warmest high ever record in February.

Strings of at least 4 days in a row with highs of at least 50 degrees in February
have happened in Southwest Michigan in 5 other years since the mid 1860s: 1930 had
7 days in a row from the 19th through the 25th, 1976 had 4 from the 24th through
the 27th, 1994 had 4 days from the 17th through the 20th, 1998 had 4 days from the
25th through the 28th, and finally the year 2000 from the 22nd through the 27th.
In that year from the 4th through 9th of March highs were mostly in the 60s, on
the 8th and 9th highs were in in the 70s.  The current event, which is two days
long and is expected to last through the 24th, would be 6 days in a row, making
it the 6th time we have seen such a string of warm weather this early in the season.

What sort of temperatures followed those warm spells? In 1930, the first 7 days of
March averaged 1 degree below normal, in 1976 the first 17 days of March averaged
3 degrees below normal, in 1994 the last week of Feb and the first 3 days of March
averaged 14 degrees below normal.  In 1998 the first 3 weeks of March averaged 5
degrees below normal.  Finally, for the long string of warm days in 2000, the daily
mean temperature averaged about 1 degree below normal from the 10th through the 19th
of March.  In conclusion having strings of days in a row with highs of 50 or warmer
in late February is unusual but not unpresedented, and typically at least a week of
colder than normal temperatures typically follows this sort of event in Southwest Michigan.
