Areas of the Pacific Northwest and Lower Mississippi Valley that have
experienced record high temperatures recently will be cooling down going
into the middle part of this week. A strong cold front pressing inland
off the northeast Pacific and through the Pacific Northwest tonight into
Tuesday will drop temperatures to below average across the Pacific
Northwest Tuesday and Wednesday. Meanwhile, another cold front currently
moving south into the Gulf coastal region will also be delivering cooler
temperatures for areas of the Lower Mississippi Valley that also have seen
record highs over the past weekend. To the north of this front along
the Gulf coast, an area of high pressure will stretch from the Southern
Plains, eastward across the Mid Mississippi Valley and Ohio Valley.
Clear skies and dry air associated with this area of high pressure will
support much below average morning low temperatures both Tuesday and
Wednesday morning across these regions.
While cooler temperatures move into the Pacific Northwest and Gulf coast,
heat will be building across the Northern to Central Plains over the next
two days, with much above average temperatures expected. This hot spell,
however, will be short lived with cooler temperatures expected across
these regions by the end of the week. The hot temps expected across the
Northern to Central Plains over the next two days are not expected to
produce any records.
Areas of New Mexico and Arizona that have received some much needed rains
over the past few weeks will begin to move toward a less active
precipitation pattern this week. Scattered monsoonal showers are still
expected across the Southwest into the Southern Rockies, but precipitation
totals are expected to be less than previous days. These regions continue
to suffer from severe to exceptional long term drought conditions.
The above mentioned cold front sinking into the Gulf coastal regions early
this week is expected to become stationary along the Gulf coast and into
the Southeast. Showers and thunderstorms should be active in the vicinity
of this front over the next several day, producing locally heavy rains and
isolated flash flooding.
