High pressure move in

(July 3, 2014) – A rare polar front is pushing in cooler air this morning.  Temperatures through Saturday will be about 10 degrees cooler than the normal for this time of the year.  Meanwhile there is a solid chance that we will go another week without hitting Indianapolis’ first 90-degree day of the year.  How long can that streak continue?

For today, the weather may top yesterday’s weather for some.  If you’re heading out to the lake you may even need a blanket to stay warm!  Highs today will struggle to hit the mid-70s with most of the day seeing temperatures in the low 70s.  The winds will be out of the north.  I was expecting a breezy day as we see high pressure building to our west and sliding in, but model data only shows winds at 5–10 mph.  Isobars are spaced fairly widely between the passing front and high pressure to our west.

Temperatures will remain cool through Saturday with highs in the upper 70s on the Fourth and near 80 for Saturday.  Things do warm up on Sunday with highs expected to hit the upper 80s.  I am keeping the rain chance out of this Sunday’s forecast but it does appear that rain showers may arrive after 9 p.m. on Sunday.  Monday looks to be stormy with another mid-level low sliding to our north.

Tropical Tracker

Precipitation is filling in around center this morning

Across the U.S., we are still tracking Hurricane Arthur.  The storm hit hurricane strength this morning and is the first Atlantic hurricane of the season.  Hurricane warnings have been posted from Surf City to Duck Pamlico Sound along the Carolina coastline.  A hurricane warning means hurricane strength winds (74 mph or greater) can be expected within 24 hours. Arthur will not affect us directly but indirectly may play a role in our comfortable weekend.  The counterclockwise rotation of the tropical low should help to deepen and stall out the trough that will move in today and tomorrow.  The speed and location of the storm will also play a role in the trough lifting out of the state allowing us to resume a more normal summer time weather pattern.
