south east of peninsula will be affected by instability condition during cold wave.

hi..
some time the cold mass that driven by Siberia high pressure to Arab Peninsula ,good for south east area.

the Arab peninsula will see a very clod wave and Freezing temperature because of this mass while interacting with thermal extending of red sea trough with south west Streams in mid and high level of troposphere in south east region!!
that caused some times Instability condition.
attached with thunder shower.

south west Streams..and good moister in 850 Mb and not bad for 700mb..
also i found a north east-west humid wind toward mountain of UAE and Oman..
(could be instable because of red see trough and cold air passing above warm water of gulf)
i think that enough for some thunder shower..
and i think we will see some local heavy Cloud over Arab Gulf and East of Qatar.

this condition will be very Explicit during cold wave.

so i think some Isolated T-S will be form next two days there inshaallah.

to the maps for GFS06z ..today:

17/12 15z
