Weather It Is (A Lot of Dust, Heat)

Good Afternoon:

Light wind, statically stable temperatures, and a persistent flow from the desert (to our east) has led to  a build up of dust.  It's also leading to fog as there is enough moisture left to combine with the dust to create many small (fog) droplets.

Our dust forecast maps (shown on our web site) indicate that elevated levels of dust should persist  into Thursday (not Wednesday as being reported in some quarters).

Meanwhile, the heat should continue to build as the week progresses.  While Shabbat is suppose to be the hottest day, there is a 30% chance that Sunday will be even hotter.

The first day of Rosh Hashanah should lead a cooling trend, but there will be no rapid drop off in temperatures, but a gradual cooling towards the Yom Kippur.

At the moment, we don't see the few days before Sukkoth as being particular warm, but pleasant skies, warm temperatures, and a few fair weather clouds should preface the holiday.

For those wondering about the forecast on our web site, we indicate sunny skies.  The forecast dust amounts are not high enough to trigger a warning on the forecast site, but it is apparent that the length  of time for which we will be affected by these relatively low concentration dust amounts could lead to health problems in those who more easily suffer from atmospheric related illnesses. Also, dust amounts will be higher in some of the mountain areas, especially in the area of the southern deserts.
