Corresponding HREF signal (00z init) which strongly indicates the maturation of a few supercellular clusters in E Saskatchewan by late afternoon/early evening.

[CG15Wx @cycloneguy15]

Intrigued by the potential for some well-structured convection in Canada this evening. Low-level wind profiles will rapidly inflate around 00z in tandem with a stabilizing BL - any established (super)cells in this environment would likely attain classic ''mothership'' appearances

[John Homenuk @jhomenuk]

The details and intricacies are impossible to sift through at this range. However, a variety of ensemble guidance is strongly suggesting a major uptick in severe weather potential across the Northern/High Plains starting next week.

[CG15Wx @cycloneguy15]

Can easily tell where the deepest updrafts (and their overshooting tops) are pulsating on visible satellite. Pretty common behaviour for newly-developed, small tropical cyclones as concentrated vorticity supports strong centralized convection

[CG15Wx @cycloneguy15]

Newly-named #Amanda features a pretty healthy appearance for a compact tropical storm. Persistent, vorticity-rich convection & the associated hot towers will promote strengthening (potentially up to brief HU status?) before entering an increasingly dry environment by the weekend

[CG15Wx @cycloneguy15]

The resultant cyclonic shear vorticity + strong upper divergence will yield a conducive environment for increased genesis potential. Pretty classic to see something like this occur in developing strong-super Ninos as enhanced westerly anomalies extend the MT much further eastward

[CG15Wx @cycloneguy15]

Will be worth watching for low-latitude genesis in the far eastern WPAC around midmonth. A robust equatorial rossby wave - amplified by low-frequency + KW forcing near the dateline - will trail westward & provide a boost to low-level westerly anomalies in the deep tropics.

@NickKrasz_Wx HAPPY BIRTHDAY NICK!!!!

[CG15Wx @cycloneguy15]

@NickKrasz_Wx interesting, i always found the ball/cube dual pretty difficult

[CG15Wx @cycloneguy15]

90E is classifiable as a tropical cyclone ATP. Can easily see its vigorous low-level circulation near the convective mass that concentrated vorticity for the cyclone overnight; also note the "curved" band of cool returns on LL microwave imagery in association with these features

The first case of EPAC TCG occurring this far westward (~130W) is pretty telling of an incoming strong-super niño given the bout(s) of anomalous westerlies that accompany the development of such events - note the strong MJO pulse currently passing through the region

[CG15Wx @cycloneguy15]

90E has been officially designated as the first invest of the Eastern Pacific hurricane season as of today - June 1st, 2026. Can already see a fairly concentrated vorticity maxima that'll gradually strengthen as it rolls up from the monsoon trough over the next couple days.

@WeathermanAAA_ Very favorable orientation & strength of the low-level flow to allow for vortex shedding off those islands - also note the marine stratocumulus which is common thanks to enhanced trades in the region.

Absolutely gorgeous Karman vortex street occurring over the canary Islands this morning.
